描述

Speed of sound calculations for live sound engineers.

The Speed of Sound
Calculated using the temperature, humidity and pressure.

Delay Time and SPL
The time taken to travel a given distance and the drop in SPL with distance.

Air Attenuation
The amount each frequency band is attenuated depending on the temperature, humidity and pressure. Only frequencies above 2kHz are significantly affected. The attenuation in dB takes into account the distance.

Wave Length
Calculates the full, half and quarter wavelengths for a given frequency. This is useful when designing sub arrays.

Period
The period for a given frequency for full, half and quarter periods.
