Noise Meters
-
Here you will find a full range with an industrial standard noise meter / sound meter to suit every requirement. With the portable noise meter you can carry out measurements quickly to gain control of a situation or to set the sound meter to take timed measurements. The noise meter is important for all industries, especially by using it as a mobile noise meter which is able to assess office stress levels or street noise levels. Often problems arise from noisy neighbors or if bars and restaurants are in residential areas and produce noise levels after 10 pm in excess of what local laws permit. A noise meter / sound meter will help here.We can assess which noise meter or sound meter you require in relation to the issue you have and the relating laws (requirements regarding a sound meter and a sound meter’s usage vary depending on the country). We also have noise meter microphone extension cords, tripods, sound meter calibrators and calibration certificates for most noise meter models.

Response Dynamics Vibration Engineering, Inc.
Effective vibration isolation is critical to the performance of many systems. It is often much more challenging than expected because the structural dynamics of the supporting structure, and the isolated structure, also affect the isolation performance. Isolation resonances can often create other vibration problems and confound an engineering team. We have successfully designed vibration isolation into countless systems over the years using unique custom solutions as well as adapting standard components and applying them properly to the design.
