Sound_sound wavesLength calculation

Hey guys I am trying to figure how to calculate the specific sound frequencies of the environment, extract them and try to find the wavelength of those specific frequencies. Any one has any idea how to do this? Thanks in Andvance!!

… which environment?
That’s probably a very complex calculation, but if you are talking about thin but long empty rooms (corridor) you can maybe find approximations by using formulas of “pipe with no/one/both ends open” , like > Standing sound waves

given a specific sound speed , frequency and wavelength are just inversely proportional. You probably know better than me. (Wavelength = soundspeed / frequency) Wavelength - Wikipedia
