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 space. This noise can interfere with production and ultimately cost your company money.
Here are 10 tips to improve the Sound Transmission Class (STC) between rooms. STC is described below the tips.
Sound walls, noise barriers, acoustical walls are an important tool for environmental noise reduction. Here are 9 tips to maximize the effectiveness of these walls.
Noise Engineers has been assisting in monitoring and evaluating the noise radiating to greater sage grouse leks near a new mining operation in Nevada for two seasons. The noise thresholds were set based on the pre-project noise levels measured in 2013. We are conducting continuous noise measurements during mating season to prevent impacts from the…
VIBRATION MEASUREMENTS Forced vibration is a time-varying disturbance applied to a mechanical system. Vibration sources are generally broken out into three categories: continuous, impulsive, and intermittent. Vibration can be measured using an accelerometer. An accelerometer is made of a piezoelectric material that gives off a small voltage when it is moved. This signal is…
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.…
When evaluating a space that has too much echo or the sound level is too high, reverberation time is generally used. Reverberation time is a measure of how long sound stays present within a space after it is made. More specifically, reverberation time is defined as the time required for the level of sound…
In this podcast and blog, I’m going to talk about road noise projects. Any time a road is expanded, moved, modified, or a new one is built and there are residences, schools, parks, or churches nearby, a noise impact study needs to be conducted. The study looks to see if sound walls are justified. Sound…
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…
