You can see the video of our conversation at: Acoustic Camera Video Acoustic Camera The acoustic camera that we use consists of 256 microphones with a camera in the middle. The array of microphones is used to identify the differences in noise levels and is overlaid on the photo of video from the camera. The…
You can see the video of our conversation at: Industrial Enclosure Video Enclosure Installation Recently, Noise Engineers installed a hard metal acoustical enclosure at a factory in Aguascalientes, México. The noise from a press causes worker noise exposure levels to exceed the Mexican limits. The noise from the press is more than 20 dBA higher…
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 and/or predict the noise passing between spaces. Exterior to Interior Sound Isolation In…
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 levels in this truck assembly plant are between 85 and 95 dBA. The primary noise…
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 room acoustics. The heating, ventilation and air conditioning (HVAC) systems are being replaced. Sound Solutions is: reviewing…
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 acoustical absorption is used, including: Restaurants Factories Gyms Pools Shooting ranges Churches…
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 components (windows, walls, roof, doors) provide interior noise levels below the required DNL 45…
Noise Expert has started providing acoustical products. They provide them, deliver them and can install them. They are focusing on four different products: acoustic wall panels loaded vinyl fiberglass absorption metal barriers/absorption NE Acoustic Panels are generally made with a 6 pound per cubic foot density fiberglass core wrapped with a fire retardant fabric…
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 lab: Inner and Outer Dimensions The entire wall and acoustical absorption…
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 $100,000 and $200,000. I found it to be very helpful,…
