To realize an environment testing apparatus which can simultaneously carry out an acoustic test and a temperature test of an object to be tested.

A film 3 passing sound, but not passing fluids sections the interior of the testing apparatus into a part where an acoustic generation means 1 generating sound and also a flow of a fluid and a discharge means 4 discharging the fluid are set, and a part where a temperature control means 2 and an object to be tested are arranged. The film 3 is supported by a supporter 6 like a grating.
