Sound energy will cause temperature rise but it will be hard to measure outside a controlled experiment in a lab. One reason is that most of the time, it isn’t a lot of energy converted to heat in the air and source of sound isn’t high energy to begin with relatively speaking.
A 50 W sound system might drive a speaker to produce a few watts of actual sound energy and, in a regular room, that is pretty loud. Loud enough that most people won’t tolerate it. It would be hard to detect a temperature difference even if these few watts converted to heat. Most of the heat would come from the electronic equipment, the lights in the room, the body heat of people inside – all of which release much more heat into the room.
