Acoustics First releases video on Vibration Isolation

Acoustics First has conjured up yet another video demonstration. As the fourth in a series designed to help explain common acoustic principles, this video briefly reveals what is necessary to provide vibration isolation.

VIBRATION ISOLATION DEMONSTRATION: Controlling Mechanical Sound Transmission

As the quandary of vibration isolation can quickly prove to be obtuse and relatively difficult to understand. Common problems like footfall from upstairs neighbors, industrial noise from machinery and HVAC equipment or isolating speakers and scientific devices can require completely different approaches. Most often, an on site assessment should be completed by a qualified engineering professional to determine an appropriate acoustic solution. In many cases the solution will require a modification to the structure and implement more than a single strategy.

This simple vibration demonstration challenges to provide a basic understanding of how acoustical materials may be used to prevent the spread of mechanical noise and vibration through existing structures like walls, floors and ceilings.

In this acoustic demonstration, a surface mounted piezo transducer connected to an analog meter will register levels of sound vibrations transmitted to the table. A vibrating device placed directly on the surface will transmit sound vibrations and resonate loudly throughout the table. These vibrations will register on the analog meter. By inserting isolation materials between the device and the surface, the mechanical sound transmission is reduced and sound no longer registers on the meter.

DIFFUSING / SCATTERING SOUND: Sound Diffusion Explained

Acoustic Diffuser DemonstrationAcoustics First has just released another in a series of videos to help explain acoustical principles using simple, easy to understand video demonstrations. This latest demonstration tackles the mystery of acoustic sound diffusion. Using an array of ping pong balls to represent sound visually, this video simply demonstrates what occurs when sound strikes the surface of an acoustic diffuser. First, you will see what happens when sound hits a flat reflective surface with no acoustical treatment. Acoustic Sound DiffuserThe balls all bounce at the same time and in the same direction. This represents what happens to the sound when it hits a flat reflective surface like a wall. Then you see what happens when sound hits an acoustic sound diffuser. You will immediately notice the energy of the wave of balls is scattered in all different directions as well as deflected at different time intervals. Diffusers, disperse or scatter the sound like crowd control, preserving the sound to maintain sound clarity without destructive interference. This is the basic principle behind acoustic sound diffusion.

The Music Producers Guild Helps Define A New Industry Standard

The Music Producers Guild’s Mastering Group has achieved a significant breakthrough for all recording artists and other copyright owners by working with the European Broadcasting Union (EBU) to create an industry standard for embedding ISRCs within digital music files.

This major step forward will make accurate file identification and content tracking much easier and could help royalty agencies develop more precise systems for payments, thereby safeguarding the incomes of all artists and copyright owners when their recordings are played on air.

MPG Mastering Group board member and Alchemy Mastering Engineer Barry Grint, who led the initiative, says: “ISRC stands for International Standard Recording Code. Every song released – and indeed every version of that song – is allocated a unique ISRC by the record label. In the past the ISRC information was included within sub data streams of a CD, so a track could be identified by its associated ISRC.

“However, now that we have entered the digital age and are increasingly using digital WAV files, the ability to securely associate ISRC data with specific tracks has been lost because the only common way to incorporate ISRC into a WAV file is via the file name. If someone renames the file – or if the name is truncated or amended by a software program – the vital ISRC information can easily be lost. Unfortunately many record companies are not aware of this and simply assume that ISRCs are being embedded into WAV files. Technically that just isn’t possible so many mastering engineers were simply adding the code to the file title, which was an insecure practise.”

The MPG Mastering Group recognized that this was a major problem and that the industry needed an approved method for embedding ISRC data within a WAV file. Fortunately the EBU had developed the Broadcast WAV File (BWF), a variant of the WAV file for use by broadcasters. Although this variation allows for metadata to be added within the file, no standard had been defined as to how and where the data should be stored. Also workstation manufacturers offering the ability to create BWF files did not have a consensus as to the fields in which data should be entered.

Barry Grint approached the EBU and asked them to adapt the BWF standard so that ISRC’s could once again be included in metadata in a regular way.

“The new system is simple to implement and the MPG is encouraging workstation manufacturers and record companies to use BWF in preference to WAV as the standard specification for file exchange,” Barry Grint says. “Once adopted, this system will allow ISRC to flow through the whole production chain. iTunes and other aggregators will be able to pull the ISRC through during encoding and broadcast playout systems can easily be adapted to recognise the ISRC, making airplay reporting far more accurate.

“This is a major step forward for the music industry as it gives us the opportunity to identify with certainty every digital Master file regardless of how that file is named. We would like to thank the team at the EBU for recognizing the importance of this to the MPG and the Music Industry worldwide and the speed with which they were able to bring this about. By making ISRC the cornerstone of asset management and royalty reporting, we should be able to ensure a more accurate system of royalty payments and writer/performer credits, thereby supporting the income of all recording artists and copyright owners well into the future.”

House Research Institute Outlines Five Ways Musicians Can Protect Their Hearing in 2012

Los Angeles – January 11, 2012 — As the 2012 NAMM Winter Show approaches, musicians from all over the world are eagerly anticipating the most recent music gear developments and exciting equipment innovations. House Research Institute (HRI) [NAMM booth 1292, Hall E] will be on hand providing hearing screenings throughout the duration of the show, while offering advice on how to protect what is unequivocally musicians’ most valuable asset: their hearing.

House Research Institute – a leading non-profit dedicated to improving the quality of life for people with hearing loss and related disorders – has outlined five simple ways musicians and music fans can preserve their hearing during 2012 and beyond:

1) Know thyself: have your hearing tested

Often, hearing loss issues are initially detected by family and friends rather than the person experiencing it. “When a person frequently has trouble understanding conversations in places where there is significant background noise, such as at parties, crowded restaurants and clubs, it might be a good time for a hearing test and an ear examination,” observes John W. House, MD, president of House Research Institute and physician at the House Clinic. Find out where you stand so you can understand and address the personal risks you may face — hearing exams take just minutes. Noise induced hearing loss begins in the higher frequencies and does not affect speech frequencies until it is advanced. Therefore, a screening audiogram is advised for those who are exposed to loud noise.

2) Know thy surroundings: avoid potentially dangerous environments

By ensuring you are in a safe listening environment, you mitigate the risk of noise induced hearing loss (NIHL). “If you have to raise your voice to be heard, you are likely in an environment with sound levels exceeding 85 dBA,” says Marilee Potthoff, director of community outreach and education at House Research Institute. Musicians and engineers depend on good hearing for their careers, but also are at high risk for hearing damage from prolonged sound exposure on the job. If you’re in the sound industry, it’s important for your hearing health to carefully monitor your sound environments that reach above 85 dBA both on and off the job, and know how much to limit your exposure. When relaxing with your personal stereo or player, we recommend keeping the volume setting at no louder than 60 percent of max. potential.

3) Use it or lose it: make the right choices in hearing protection

Educate yourself on what kind of hearing protection is truly effective. “Select hearing protection devices that provide the appropriate amount of sound reduction. Hearing protection with an NRR (noise reduction rating) of around 25 to 35 dB offers better protection for loud music environments than devices with lower NRRs. Using devices with a much lower NRR may result in significant damage to the inner ear when exposed to high level [loud] sounds,” says Andrew Vermiglio, AuD, HRI research audiologist and California State University Northridge audiology professor. Some custom ear plugs — which are available through licensed audiology clinics, including the House Clinic — offer a flatter attenuation across the frequency range and may make listening to loud music more enjoyable than standard, over-the-counter earplugs, such as foam or pre-molded plugs. Standard earplugs tend to “colorize” what you hear by filtering the high frequencies more than the low frequencies.

4) Keep it clean: Ears need good hygiene, too
Earwax may not be the most popular discussion topic in the world, but it is certainly worth knowing about. Knowing how to safely remove wax and dirt build up will help you keep your hearing on the right track in 2012 and beyond. “Never insert foreign objects into your ear canal, including cotton swabs — instead, use a warm washcloth to gently clean the outer area of your ears or an over the counter ear wax removal solution,” says Dr. House. Other ear cleaning methods known as ear candling or coning are dangerous, not effective, and can easily damage your ear canal.

5) Make a date: Have your ears checked on a regular basis
Have your hearing checked annually. If you notice a change in the state of your hearing, seek immediate medical attention. “Annual hearing exams may help to identify potential hearing loss issues while there is still time to rectify them,” says Dr. Vermiglio. Also, symptoms such as hearing loss, ringing in the ears, dizziness or loss of balance, may be related to a serious medical condition.

So whether you are a musician, or just enjoy listening to music with friends, follow these basic steps and put your hearing first in 2012 — because once you lose it, you may never be able to get it back.
