Sound insulation is the process of soundproofing an enclosed space, such as a room. This type of insulating activity is usually employed when there is a need to keep sound from filtering into or out of the space. Sound insulation techniques are often used in business settings, as well as in multi-family dwellings like duplexes and apartment buildings.

In order to prevent background noise from interfering with the recording process, singers and musicians create their vocal and instrumental tracks in a soundproof recording booth. Because the booth prohibits the introduction of sounds from outside the space, there is nothing present to distort or interfere with the quality of the recording. The audio tracks containing vocal performances and the various music tracks are captured exactly as the performers hear them.

In living space, sound insulation normally involves the installation of insulation in walls, under floors and above ceilings. This can be especially important in apartment buildings and other structures where people live in close proximity. The inclusion of the insulation between apartments to the side, above, and below helps to ensure all the residents enjoy a measure of peace and quiet, even when others in the building are playing music or having a party.

In an office setting, it is not unusual for the individual offices of managers to be insulated for privacy. This makes it less likely for confidential discussions between an employee and a manager to be overheard by others working elsewhere on the floor or near the door of the manager’s office. In like manner, conference rooms are often treated to a sound insulation treatment, ensuring discussions taking place within that space are not overheard by others in the immediate vicinity.

Soundproofing insulation is a man-made material that is designed to absorb sound waves. This type of insulation is commonly installed in recording studios, meeting rooms and concert halls. The purpose of soundproofing insulation is to improve the enjoyment of the sound in the initial room through the removal of external noises, and to eliminate the traveling of the sound waves outside the room.

Soundproofing foam is a building material used to control the transmission and absorption of sound. This material can be used to achieve two distinct goals when it comes to sound control. First, it is used in homes and commercial buildings to block sound from the outdoors, keeping the interior of the space quieter for the occupants. Soundproofing foam can also be used to absorb noises in recording studios or theaters, which reduces echo and improves the quality of the sounds.

To understand how different types of soundproofing foam can be used, one must first understand how sound waves and noise levels are measured. The ability of an object to block sound is measured by its Sound Transmission Coefficient (STC) rating, which can range from 0 to 100. A wall with a STC rating of 50, for example, means that noise levels on one side of the wall are 50 decibels higher than on the other side. Sound absorption is measured using the Noise Reduction Coefficient (NRC), which generally falls between 0 and 1. This number shows the amount of sound absorbed by an object, and the higher the NRC value, the more noise is absorbed

A soundproof ceiling is a ceiling that has been designed to cut down on the noise that is transferred from overhead to the area below. A soundproof ceiling is a nice addition for people who live in apartments, but, surprisingly, many people who live in private homes are also interested in soundproofing their ceilings.

A soundproof door is a door which has been designed or retrofitted to cut out as much external noise as possible. However, a soundproof door is also very dependent on a well-designed frame, or sound can leak around the edges of the frame. Unwanted noise can also filter through walls and windows, which are an important consideration for people who are attempting to soundproof a room or building.

There are a variety of situations in which a soundproof door can be useful. Musicians and recording studios rely on such doors to keep sounds from getting out, both for the comfort of the neighbors and for the benefit of other musicians and recording facilities which could be compromised by sound leakage. Soundproof doors are also used to seal noisy rooms like boiler rooms and entrances to factory floors. People can also utilize soundproof doors to keep unwanted sound out of their homes.

Acoustics studies the sound and how it behaves in various environments

Acoustics studies the sound and how it behaves in various environments. Sound effects such as absorption, reflection, refraction or interference are also studied by acoustics. The broad acceptance of the term ‘acoustics’ refers to all the aspects of sound. Until not long ago, the notions ‘acoustics’ and ‘sound’ referred to waves and elastic vibrations that humans could hear. However, in the twentieth century, the development of technology and science has led to the broadening of the field of acoustics, in that it now comprises aspects not directly related to the hearing process, such as intensities and frequencies which are above or below the audible limits of humans.

When speaking of sounds, most people think of the vibrations in any type of medium, which can cause the sensation of hearing. Any unwanted sound is perceived as a noise. The term is definitely subjective, since what is music for one person can very well be noise for another. When such unwanted sounds are excessive, their effects can be destructive, which is now known by the name of noise pollution. Adverse noise effects fall into three categories, physiological, psychological and communicational. Unfortunately, there aren’t any known and adopted remedies for the last two categories. Noise pollution is a complex problem and surveys show a disturbing fact, that noise levels are continually rising in cities.

As far as the sounds inside buildings go, we can speak about two main ways of transmission. Firstly, the sound emanated from either human activity or mechanical noise inside the building travels airborne through walls, ceiling or floor. Sounds from human activity include loud voice or amplified systems. Mechanical noise refers to the sounds produced by elevators, generators, air conditioning systems and so on. Secondly, interior sound can be transmitted not through air, but through the building itself. The former is easier to abate than the latter through wall or ceiling assemblies which meet certain established performance standards.

Statistics say that millions of employees are exposed to noise in the office, and therefore are subjected to all the risks that come along. Work-related stress and accidents which occur because of masked warning signals are just two of them, not to mention the lack of productivity and efficiency on the part of the office workers. Noise represents a safety issue, butt also a productivity issue for the employees. The office should be a quiet place to work and an office with good acoustics will provide the employees with the ability to concentrate and not be distracted. Reducing the intensity of sounds is called soundproofing. Soundproofing can be accomplished in a variety of ways. The distance between the source and the receiver could be increased, sound wave energy could be blocked or absorbed by means of noise barriers, sound baffles could be used as damping structures, or antinoise generators could be activated. With soundproofing, noise can be affected in two ways: it can be either reduced or absorbed. Noise reduction implies blocking the sound wave passage with intervening objects. The absorption of noise refers to echoes and reverberation being suppressed.

The office environment is a place for many acoustic challenges. If sound levels in the office affect efficiency and productivity, the good news is that there are solutions for office noise control. There are many soundproofing materials which improve the sound quality within the room and eliminate the transfer of sound from one room to another. Office noise control is a must for a quiet environments in which employees can concentrate and be efficient in their work. Soundproofing materials play an important part in office noise control, since other methods have failed to show efficiency. Not only are soundproofing materials a useful barrier in blocking noise, but there are also excellent in appearance. Soundproofing materials add an aesthetical touch to your place of work, not to mention that they are fire rated.

The Difference between Sound Absorption and Sound Blocking

The Difference between Sound Absorption and Sound Blocking

Sound is like water. It doesn’t have a shape or form, but molds itself to its surroundings. And like water, sound can be absorbed by some materials and contained by others.

Soundproofing products trap the sound. They contain the sound within a space, making it impossible for the sound to move to other parts of the building. They also stop unwanted sound from entering the room.
Sound absorption products soak up sound. They absorb sound waves and prevent them from bouncing off the walls. They improve the quality of the sound within a room.

What’s STC?

To be able to compare the performance of different soundproofing products, we rate them by how much sound they can block. This rating is called STC, which stands for Sound Transmission Class.

Generally, the higher the STC rating, the better the material is at blocking sound.

What’s NRC?

To be able to compare the performance of different sound absorption products, we rate them by how much sound they can soak up. This rating is called NRC, which stands for Noise Reduction Coefficient.

Generally, the higher the NRC rating, the better the product is at absorbing sounds.

2 Types of Soundproofing Products

There are 3 types of soundproofing products: sound blockers, sound absorbers and composites. The origin of your sound issue will determine the best product type for you.

Sound Blockers

If the sound you need to control is not originating from the same space as you, sound blockers are the best solution. Sound blockers stop, reflect, or reroute noise to prevent its transmission through a surface. They are hard, heavy, and flexible.

Use sound blockers to stop sound from traveling from one space to another. Sound blockers can be installed in walls, doors, floors, and ceilings.

Sound Absorbers

If the noise you need to control is originating in the same space as you, sound absorbers are the best solution. Sound absorbers soak up, trap, and dissipate noise energy. They are light, porous, and soft to the touch.

Absorption products control noise within an enclosed area, improving the sound quality. Because they usually are a finishing product, they are available in many different styles and colors to match any decor.

What is Sound?

Sound is vibration transmitted through a medium. When we think and talk about sound, though, we mean those vibrations in air molecules that can be picked up by human ears.

Sound as a Wave

Sound energy moves the molecules within the substance through which it travels, just like ripples in a pond. Sound waves spread in a circle from the source, becoming less intense with distance.

Sound is like water. It doesn’t have a shape or form, but molds itself to its surroundings. And like water, sound can be absorbed by some materials and contained by others.

Sound waves need a medium through which to travel. There’s no sound in space, and the most common sound conductor on earth is air. But sound waves can also pass through solid materials. Which is why Soundproof Cow is in business!

How is Sound Measured?

You can look at water and see that either the surface is smooth, or it has a lot of big waves. You can even pour it into a container and measure it. Since sound doesn’t look like anything, how can you tell how “big” or “loud” it really is?

Sound is measured in two fundamental ways: frequency and amplitude, or as they are more commonly known, pitch and volume.


Frequency, also known as pitch, is the space between waves of sound, or how many times a sound wave oscillates (moves up and down) in one second. The frequency of a sound is like the current in a body of water. The current tells you how fast the water is moving from one point to another.

Frequency is expressed in Hertz (Hz). Hertz is a measure of frequency per unit of time. For example 1 Hertz = 1 sound oscillation per second. The average person can hear sounds with frequencies between 60Hz and 23000Hz. The average cow can hear sounds with frequencies between 20Hz and 35000Hz.

A high-pitched sound is like a ripple in a pond: it’s small, has low power, moves quickly and can easily be controlled and redirected. A low-pitched sound is more like a tsunami or tidal wave: large, slow moving, strong and difficult to control or redirect.

Noise Control Frequently Asked Questions

We have listed below some of the most common questions and their answers in hopes of providing basic knowledge related to noise, and noise control products and systems.

What is Noise?
What level does noise become harmful to me?
What is dB-A?
What does 85 dB-A sound like?
What is N.R.C.?
What is STC?
How do we prevent equipment from overheating in a noise enclosure?

What is Noise?

Noise is defined as unwanted sound. Unwanted sound can be hazardous to your hearing or can be simply disturbing, interfering or annoying. Sound does not have to be loud to be unwanted.

What level does noise become harmful to me?

Driven by OSHA standards, corporate safety departments and insurance carriers, noise levels are typically set 85 dB-A as the high noise level. Individuals exposed to this noise are permitted to work an 8 hour shift with hearing protection. Administrative and engineered controls should be taken to reduce the employees noise exposure at 85 dB-A.

What is dB-A?

The sound pressure level designed to closely reflect the response of the human ear. We are less sensitive to low and high frequencies, thus an “A” weighted noise level is what we hear.

What does 85 dB-A sound like?

Buses, motorcycles, and pneumatic tools at 50 feet. You must raise you voice to a near shout to speak over 85 dB-A.

What is N.R.C.?

The Noise Reduction Coefficient of a product is the average absorption across four octave band center frequencies. (250 Hz., 500 Hz., 1000 Hz., 2000 Hz.) You can roughly estimate that a product with an NRC .75 will absorb 75% of the sound energy that hits it. The highest level is NRC 1.0.

What is STC?

A single number decibel rating of the transmission loss properties of a product. Doors, windows, walls, floors, etc. are tested to determine how much noise passes through. The testing determines a product’s STC. The higher the number the better.

How do we prevent equipment from overheating in a noise enclosure?

Silenced ventilation systems can be as simple as a blower system that moves existing plant air through the enclosure or as complex as separate HVAC systems. Silencers on the intake and exhaust will prevent the passage of noise in or out of the enclosure.

How do we maintain access to the equipment for maintenance?

Maintenance access is a key consideration in the design of an enclosure. Lengthy discussions with the equipment operators and maintenance personel will ensure proper access is provided to all required areas. Swing, sliding, and removable doors and plugs are how most access is obtained.

Why is the machinery louder in my shop than what the manufacturer’s data shows?

Most equipment is tested in a free field condition, a room with no hard surfaces that reflect sound. Most industrial facilities have hard floor, hard walls, and hard ceilings. The reflected sound can build up to create a higher noise level. When the equipment is placed near other machinery making noise you can build noise as well. Isolating each piece of equipment can dramatically reduce the noise levels.

Why do I care about noise at my property line?

Noise is measured at your lot line. The neighbor’s home may be 400 feet from the lot line but codes state that you can not send noise off your property. Communities may or may not have a noise ordinance for you to follow. If they do not have an existing ordinance you can be assured they will write one directed at you.
