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.

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

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?
How do we maintain access to the equipment for maintenance?
Why is the machinery louder in my shop than what the manufacturer’s data shows?
Why do I care about noise at my property line?

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.

Soundproofing, Noise Control, Noise Reduction

Read a little about what the terms mean or dive rightinto our acoustic products on the right. So what does it all mean? All soundproofing and noise control terms cover a lot of ground in the acoustics and noise control industry. All our products are broken into noise barrier materials – http://www.allnoisecontrol.com/SoundBarriers.cfm and noise absorption materials – http://www.allnoisecontrol.com/NoiseAbsorption.cfm. There are 2 main ways to deal with sound problems.

We’ve found that if you are looking for noise control, your typically looking to block noise (noise barriers) in the INDUSTRIAL – http://www.allnoisecontrol.com/applications/industrial_noise_control.cfm, corporate or COMMERCIAL- http://www.allnoisecontrol.com/applications/offices.cfm markets looking to quiet noisy equipments, facilities, block noise from room to room ( or any space to another ).

If you refer to soundproofing, your typically looking to absorb sound or dealing with echo & reverberation problems. These are typically in institutional ( schools, auditoriums), houses of worship – http://www.allnoisecontrol.com/applications/houses_of_worship.cfm, architectural acoustics – http://www.allnoisecontrol.com/applications/architectural_acoustics.cfm, theaters – http://www.allnoisecontrol.com/applications/home_theaters.cfm and other similair. Typically sound created by humans ( voice, footsteps, activities ) and/or music, media and theater and other various shared and large space.

Noise Control

Noise control is an active or passive means of reducing sound emissions, often incentivised by personal comfort, environmental considerations or legal compliance. Practical and efficient noise control is wholly reliant on an accurate diagnosis of what is causing the noise, which first involves finding the source of noise. Once the source of noise has been found, the focus is reducing the noise at source by engineering means.

The most common noise sources can be divided into aerodynamic such as fans, pneumatics, combustion, etc and mechanical such as impacts, friction, etc. Effective noise control focuses on reducing the noise from these sources as close to the source as possible. Noise control for aerodynamic sources include quiet air nozzles, pneumatic silencers and quiet fan technology.

Types of noise control

There are four basic principles of noise control:

• Sound insulation: prevent the transmission of noise by the introduction of a mass barrier. Common materials have high-density properties such as brick, concrete, metal etc.

• Sound absorption: a porous material which acts as a ‘noise sponge’ by converting the sound energy into heat within the material. Common sound absorption materials include open cell foams and fiberglass

• Vibration damping: applicable for large vibrating surfaces. The damping mechanism works by extracting the vibration energy from the thin sheet and dissipating it as heat. A common material is sound deadened steel.

• Vibration isolation: prevents transmission of vibration energy from a source to a receiver by introducing a flexible element or a physical break. Common vibration isolators are springs, rubber mounts, cork etc.
