    Sound instrumentation for measuring sound

    What is the difference between sound and noise? Clearly more than the loudness only. Although an aircraft is very noisy, a mosquito at night-time can be more than enough to spoil a good night`s sleep. Instead of looking at the loudness only as a criterion for the degree of noisiness, we shall simply regard noise as what it is - viz. unwanted sound.

    Sound instrumentation for vibration

    Vibration is simply defined as the variation of an object about a fixed position. To properly define and quantify the physical characteristics of vibration, however, is much more complex - account must be taken of the direction, frequency and magnitude of vibration. Then, what properties should be measured? Is it appropriate to measure the displacement of the vibrating object as a measure of its amplitude, or should we instead measure velocity, or acceleration? What are the conventions for measuring...

    Sound level meters & Noise dosimeters for Vehicle noise measurements industry

    The noise from vehicles such as cars, buses and trucks is wide spread with many people being affected by these noise sources in their daily lives. All modern vehicles will be designed to meet strict safety and emissions standards as well as noise output levels. All vehicles sold in the EU must comply with a range of noise directives to ensure that they meet these specified noise levels when they are sold and many countries enforce regular checks over the life of the vehicle. Motor Sport noise is a often a...

    Sound instrumentation for building acoustics

    The field of building acoustics consists of two parts; Room Acoustics which deals with sound propagation in a room and Building Acoustics, which deals with sound propagation between rooms. Typically, room acoustics is related to the quality of sound, e.g. concert hall acoustics, while building acoustics is more related to unwanted sound, i.e. when you want to hear as little as possible of what is going on in adjacent rooms....

  • Noise monitoring solutions for environmental noise and vibration

    Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture,...

  • Noise monitoring solutions for Pass-by noise testing

    Traditional Field Pass-by measurements are still the only way to certify a vehicle for exterior noise emission during operation, but Indoor Pass-by provides an extremely powerful and repeatable method of troubleshooting exterior vehicle noise in the controlled environment ofan anechoic chamber.

  • Noise and vibration problem solutions for transportation & infrastructure sector

    Roads, railways and airports are the largest source of transportation noise and frequently effects development land for houses, schools and hospitals. Noise sensitive developments adjacent to or affected by transportation noise require the careful assessment of these sources, either by measurement or prediction and often both. This assessment enables the correct specification of the building envelope (walls, windows, ventilators and roofs) to achieve appropriate internal noise levels in new developments. Here...
