How does temperature affect sound wave dissipation in air?

Question

Sound waves dissipate in any material such as air, but if temperature decreases or increases; how would the increase or decrease in temperature affect the dissipation?

Anders Sandberg · Answer

Yes. See equation 8-10 in this chapter, which gives sound attenuation as a function of temperature, frequency and water vapour concentration. The relationship is somewhat complicated, but loosely attenuation of sound per distance increases as the air gets colder.
