On a distant planet, an alien creature sings a sustained musical note with a wavelength of 56.4 cm. Another alien produces a note with wavelength of 56.9 cm. The atmosphere near the planet's surface has a bulk modulus of 102 kN m^-2 and its density is 0.89 kg m^-3.

What beat frequency is heard when both aliens sing simultaneously?
