Comparison of violin impulse responses by listening to convoluted signals
The impulse or frequency responses of violins have been measured both with traditional techniques (2 channel FFT analysers) and with an MLS (Maximum Length Sequence) analyser. These measured impulse responses were convoluted with an anechoic signal which was sampled during an actual musical performance, where a phonograph needle was mounted on top of the violin bridge and the acquired data then stored in digital format on a computer. In this paper the emphasis is on a better understanding of the frequency response. An attempt is made to determine which resonance peaks are important to the sound impression of a violin. The results of these tests show that the impulse response technique clearly identifies the differences between violins of different makers, and that by adjusting the frequency response of a bad violin it is possible to improve its sound.
