The casing includes a bottom section and a cover removably mounted on the bottom section for opening the casing and permitting a unit to be introduced therein. A receiving part is disposed in the bottom section for receiving a unit from the assembly line when the cover is open, and for transferring the unit to the packing line after the testing has been performed. A test mechanism is provided for testing and operating noise level of a unit disposed in the casing with the cover closed. The test mechanism includes a microphone disposed within the casing.
