摘要：
A sound testing chamber comprises a sound proof enclosure, a speaker system and an electronic noise generator system. The speaker system is disposed within the sound proof enclosure. The electronic noise generator system is electronically coupled to the speaker system. The electronic noise generator system is configured to send a signal to the speaker system to generate a sound simulating a scenario where hearing protection is desirable. A method for testing hearing protection equipment using a noise simulating booth comprises: allowing a test subject to select a sound to be played by an electronic noise simulating system； positioning the test subject within a sound proof enclosure having speakers that generate the sound； positioning hearing protection equipment on the test subject； and playing the sound in the sound proof enclosure to permit the test subject to evaluate the hearing protection equipment.
