Sound radiation characteristics and sound impression
Examining different musical instruments with HEAD VISOR
The complex sound of musical instruments is widely determined by playing technique and construction details such as size, shape, and materials. The acoustic examination of instrument sounds is one of the subjects of the “Music Acoustics” course at the Erich Thienhaus Institute of the Hochschule für Musik in Detmold, Germany. Students and lecturers of this M.Sc. course have examined the radiation characteristics of different musical instruments with state-of-the-art technology, such as the HEAD Visor from HEAD acoustics.
For each type of instrument, its construction gives it its own distinct sound color. This is shaped by the specific occurrence and attunement of overtones – even when playing the same fundamental tone.
With the HEAD VISOR technology, it is possible to isolate the individual harmonic overtones of an instrument, such as a cello, to assess them individually and to locate their place of origin on the instrument.
For example, it was possible to determine which frequencies are emitted from the middle of the instrument, which frequencies form a dipole along the length of the instrument, and at which frequencies the openings in the instrument body play a significant role for the sound radiation.
This acoustic and visual comparison of the frequency bands of a smaller cello for children (upper figure) and a standard size cello (lower figure) facilitates the explanation of the differences between the sound impressions of these instruments.
