Noise Expert Podcast Blog

We regularly give advise to solve acoustical problems.

Acoustical Absorption

Acoustical absorption is used in a wide array of settings and applications.  It is used to control echo, reduce the noise level in a space, make it easier to understand speach, and control focusing.  We now offer a Free Room Acoustics Analysis...

25 Vibration Control

MEASURING VIBRATION Vibration is a disturbance that is put onto a system. Causes of vibration can be categorized as: continuous, impulsive, and intermittent. Accelerometers (made of piezoelectric material) are used to measure vibration. Accelerometers gives off a...

24 Sound Isolation

Noise isolation is an acoustical issue we regularly confront. The two primary methods for noise to be transmitted is airborne and structure-borne. Airborne sound sources pass sound by the air which causes the partition (wall or floor ceiling) to vibrate.  The...

23 Noise Control Basics & Acoustical Product Directory eBook

Our eBook - Noise Control Basics & Acoustical Product Directory eBook is now available on at Amazon for $2.99. If you get the book please let me know if you have any comments or questions. I would like to build on this each year and make it a practical resource so...

22 T60 Reverberation Time

While analyzing an area containing an excessive amount echo or the noise buildup that is too high, reverberation time analysis is often used. Reverberation time is a measure of the time noise remains in a space soon after it is produced. Particularly, reverberation...

19 Theatre Acoustics

Noise Expert (acoustical engineers) recently completed an evaluation of a theatre located in Prescott, Arizona.  The challenge was that they wanted to preserved a barrel vaulted ceiling.  The ceiling is not steeply sloped – the focal point is several feet below the...

18 MRI Vibration Testing

Noise Expert regularly measures the existing vibration levels at the sites of proposed MRI machines (hospitals and clinics). The manufacturers require that the sites meet certain vibration limits so that imaging from the MRIs are not affected. Vibration measurements...
