Noise and Vibration: Uses and Effects

Noise and vibration are two elements that people come across every day. These elements do not only bring about wonderful results that are often associated with music and arts, they are also employed in various industries. Noise and vibration are needed in some industries to produce products or help in the processing of others. This makes these elements an essential part of everyday and their correct usage can be very beneficial for people and the society as a whole.

In order for noise and vibration to be very useful, they have to be produced in the right levels. Noise and vibration are measured to make sure that these specific levels are achieved. There are different measuring devices that are used to measure the level of noise and vibration. These devices also ensure that the levels of these elements are not excessive enough that may cause distortion or damage to humans. Exposure to high and excessive levels of noise and vibration are proven to cause considerable effects to humans.

The study of noise, vibration, and harshness (NVH) is essential to determine the effects of noise and vibration to people; and to help manage such effects. An Annual Noise and Vibration Conference is also held in various areas around the world to emphasize and discuss the latest updates on noise, vibration, and harshness  and its usage in the engineering of transportation technological innovations.

One example of a passive vibration isolation system is the suspension bracket of an automobile. This may not affect your cheap car insurance rate, but it definitely impacts your ride.

Common Noise and Vibration Measuring Devices

Noise and Vibration Analyzer- high performance noise figure analyzer designed to make fast, accurate and repeatable noise figure measurement.

Sound level meter- device that measures the intensity of sound at a given moment.

Noise Dosimeter- is a specialized sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time.

Vibration Meter and Analyzer- used to measure the level and intensity of vibration.

Vibration Monitoring Systems- systems used to monitor the level and intensity of vibration at a specific period of time.

PC Based Sound Level Meter- a sound level meter connected to a personal computer.
