The procedure to use the sound wavelength calculator is as follows: Step 1: Enter the frequency and velocity of the sound waves and x for the unknown in the input field. . Example: Calculate the wavelength of a sound wave propagating in sea water from a transducer at a frequency of 50 kHz if the speed of sound in salt water is 1530 m/s. Since the acoustic disturbance introduced in a point is very small the heat transfer can be neglected and for gases assumed isentropic.For an isentropic process the ideal gas law can be used and the speed of sound can be expressed as. Speed of sound in air calculator allows you to calculate speed of sound waves in air at different temperatures in different measurement units. It can also calculate the frequency if the wavelength and the medium are known or the speed of sound if its frequency and wavelength are known. rho is the density ρ and p is the sound pressure.
