| Abstrakt: | The use of the single dBA level as a hearing-damage criterion was stated by Flanagan and Guttman [J. Acoust. Soc. Am. 36, 1654-1658 1964)] to be inapplicable. It is shown by consideration of a number of industrial noise spectra that dBA levels can be satisfactorily used in practice. A level of 81 dBA or less is safe, and over 88 dBA dangerous; intermediate levels need checking by analysis. [ABSTRACT FROM AUTHOR] |
