Building a Plane-Wave Tube: Experimental and Theoretical Aspects
The design, building and testing of a plane-wave tube for measurements of compression drivers are described. Testing the device, the acoustical properties of open and closed ducts, and the capability of MLS-based measurement systems to retain the anechoic part only of the impulse response were exploited. The influence of higher modes of vibration in setting the upper limit of usable bandwidth is investigated.
