Sound is pressure — the louder the sound, the greater the pressure. The greater the pressure, the more damage it can do to your ears. If you’re in a noisy environment, it’s important to know how ...

When specifying cooling equipment, engineers are faced with myriad decisions affecting performance and layout. One critical consideration is the noise emitted. As population density rises in major ...

We saw earlier that when sound waves come from correlated sources then their pressure and associated velocity components simply add. This meant that the pressure amplitude could vary between zero and ...

Sometimes a gearbox problem can be easily identified by the sound it makes during operation. Conversely, other situations exist for which “normal sounding” and “abnormal sounding” are simply too ...
