Siren Design for Producing Controlled Wave Form with Amplitude Modulation
A siren has been developed which permits the generation of a sound pressure wave with harmonics more than 15 db below the fundamental over a broad frequency range and over a range of power output exceeding 40 db. The large dynamic range was obtained by the use of a shutter which changes the maximum...
