Speed of sound calculations for live sound engineers.
Now with metric or US units (meters or feet).
Temperature in Celsius or Fahrenheit.
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.
Frequency Attenuation
The amount attenuated by each frequency band depends on temperature, humidity, and pressure. Only frequencies above 2kHz are significantly affected. The attenuation in dB takes into account the distance.
Wavelength
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.
