Divers working deep in the ocean breathe a mixture of gases, of which 97 % is helium [12]. the speed of sound in helium is 965 m/s. how does this affect the first two formants of the diver's voices? (hint: the formant frequency is proportional to the speed of sound in the gas that fills the cavity.)
