What is Reverberation in Acoustical Analysis?
Sound waves develop in a compressible medium, such as air, when there are very short variations in pressure. A sound is what the ear perceives from this fluctuation. If the wave created by a [...]
The Effect of Wind and Temperature Gradients on Sound Waves
Sound is a mechanical wave, which means that it needs support to propagate (air), unlike electromagnetic waves that can propagate in a vacuum. It also means that sound is subject to changes in [...]
Measurement In Decibels: What Is the Difference Between dB and dB(A)?
First of all, a dB (decibel) is a ratio between two quantities that has been reported on a logarithmic scale. Moreover, dB allows a realistic modelling of human auditory perception, since the ear [...]
What Is an Acoustic Engineer?
An acoustical engineer is an engineer who specializes in the science of sound and vibration (physics). Their primary function is the control of noise or vibration that can affect individuals, and [...]
