SpeedAir - Speed of Sound

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. Make a Donation Support further development by making an optional small (or large) donation. Thanks!
