Silencieux industriels que devient l'énergie sonore

Industrial silencers: what happens to the sound energy?

When an industrial silencer has an attenuation of 40 dB at one meter, the acoustic energy transmitted is divided by 10,000. The question naturally arises: has this energy simply disappeared? The answer is no.
