Abstract
In order to instrumentally or perceptually evaluate and compare the sounds of dental turbines, a representative and reproducible procedure is desirable. DIN EN ISO 14457 (2013) specifies setup and conditions for measuring the maximum A-weighted sound-pressure level in the context of maximum noise limits, not of sound quality. However, this setup may also be used for measurements and recordings in the field of sound quality. With the aim of providing data to support the selection of an appropriate measurement setup, directivity characteristics of several dental turbines are presented and discussed in the present study. A special focus will be given to the relevance of the physical characteristics found for sound-quality evaluations. It will be shown that each component of the turbine sound can exhibit different directivity characteristics, which will affect the selection of a measurement setup suited for the desired application.
