RESARCH ON MUSICAL SOUND AND ITS FEATURES, DEPENDING ON STRUCTURAL PROPERTIES OF HEADS

Öz

In this thesis, the effects of structural features on quality of musical sound were

investigated. In the project, 12 different heads were prepared for percussion. The

properties of the quality sound as a sound-wave were evaluated so as to investigate

the effects of mechanical and structural properties on sound. In order to obtain the

pure vibrations of skins, a Mechanical Streching Aparattus (MGD) was developed. By

using the microphone and accelerometer, sounds had been recorded from heads

that streched on MGD. By using computer software, the time-dependant changes

seen in the wave forms of the voice-recordings were subjected to two and three

dimensional researches in attack, sustain and decay processes. According to the

analysis, it is understood that the concord and the corelative ratios of the basic

harmonics and the frequencies of the regular progress and voices samples in the

signal graphics are an important factor for the sound quality. In this respect; it is

determined that the voice samples for the Heads no. 6., 5. and 7 are relatively well.

However, it is detected that the differences of the musical voice samples in respect

to quality properties are the result of the excessiveness of structurally vibrating

elements and this leads to some complicated vibes.
