The acoustic radiation pattern, or beam pattern, is the relative sensitivity of a transducer as a function of spatial angle. This pattern is determined by factors such as the frequency of operation and the size, shape and acoustic phase characteristics of the vibrating surface. The beam patterns of transducers are reciprocal, which means that the beam wi ...
The economics of French instrument making consists almost entirely of very small handicraft enterprises. Faced with strong international competition, they are positioned on the top-end and concert musical instruments market, while learning instruments are rather manufactured on an industrial basis. This observation may certainly be applied more generally ...
