Document Type and Number:
Japanese Patent JP6802386
Kind Code:
B2
Abstract:
A high throughput acoustic vent structure test apparatus includes first and second elements that can removably connect with one another to sealingly enclose an acoustic cavity. A test sample holder can be enclosed in the acoustic cavity, the test sample holder having a test sample side and a microphone side, with a plurality of ports therethrough and a plurality of microphones on the microphone side connected with the ports. An acoustic source is positioned in the acoustic cavity opposite the test sample holder, and operable to generate an acoustic signal that can be picked up by the microphones through the plurality of ports. In operation, test samples of acoustic vent structures can be positioned on the test sample holder.
