Noise Engineers Podcast & Blog

We regularly give advise to solve acoustical problems.

Evaluating Sound Transmission Class

You can see our video about this topic at: Sound Isolation Video. Sound Isolation Projects Noise Engineers regularly works on sound isolation projects. Generally, it involves reducing the noise between spaces or from the exterior to interior.  Usually, we need to test...

Factory Noise Reduction

Noise Engineers recently installed acoustical treatment to a factory in Mexico.  The installation was done to reduce worker noise exposure.  In this blog we will discuss the noise problem, the treatment options, and the expected noise reduction. The worker noise...

Elementary School Acoustics – Mechanical Noise and Sound Isolation

Noise Engineers is working with Davy Architecture on the acoustics for the remodel of the Emerson Bandini Elementary School located in San Diego, California.  The primary acoustical issues being addressed are: mechanical noise, sound isolation, impact insulation, and...

Acoustical Absorption

Acoustical absorption is used in a wide array of settings and applications.  It is used to control echo, reduce the noise level in a space, make it easier to understand speach, and control focusing. Applications There are many different types of spaces where...

HUD Noise Guideline

When evaluating a site for compliance with the HUD (U.S. Department of Housing and Urban Development) guidelines, there are generally two steps. Predict the noise levels outside the proposed building If necessary, predict the interior noise level and insure the...

Acoustic Chamber

We have received several inquiries about constructing an acoustics testing lab.  There have been varying degrees of development of the plans we have received.  I thought this could be helpful, so I put together a list of factors to consider when designing an acoustics...

Acoustic Camera

I recently used an acoustic camera for three factory noise projects in Mexico.  We were tasked with identifying the noise sources and reducing the noise from many machines.  We rented an acoustic camera to help us with this process.  An acoustic camera costs between...

OSHA Worker Noise

Why Is Factory Soundproofing Important? Factories typically have high ceilings with lots of hard reflective surfaces. When sound impacts a surface it is either reflected, absorbed or transmitted. In factory spaces, much of the machinery noise is reflected into the...
