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.
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…
Sound isolation is a common acoustical concern. There are two main ways sound is transmitted from one space to another – airborne and structure-borne. Airborne noise sources transmit noise through the air which causes the wall or floor/ceiling to vibrate, the vibration is transmitted and causes sound on the other side. Airborne noise sources include:…
In this blog, I will discuss environmental noise projects. I will use cell towers as an example because we have had a lot of these projects in the last couple of year but these principles apply to any environmental noise project. The primary noise sources at a cell tower are AC units and generators.…
Sound Pressure Level Sound, or noise, is the term given to variations in air pressure that are capable of being detected by the human ear. Small fluctuations in atmospheric pressure (sound pressure) constitute the physical property measured with a sound pressure level meter. Because the human ear can detect variations in atmospheric pressure over such…
