   Abstract : Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound.

   Abstract : A phonetogram is a diagram displaying sound pressure levels (SPL) of softest and loudest possible phonation over the entire fundamental frequency range (F0) of a voice. Female singers mean phonetogram had a significantly higher upper contour than female nonsingers. READ MORE

7. 5. Critical noise factors and their relation to annoyance in working environments

   Author : Kjell Holmberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Abstract : Noise is one of the most widespread problems in working environments. Besides the obvious risk of hearing damage and masking of warning signals and speech, the effects on concentration, performance, behaviour and general well-being are serious consequences of annoying noise in the working environment.
