1. Insulation. The quality and amount of insulation placed around the exterior of the dishwasher significantly impacts noise output. 2. Tub Materials. A dishwasher with a stainless steel tub is generally quieter than dishwashers with plastic tubs. Additionally, sound dampening on the outside of the tub helps to decrease noise.
The incidence of hearing loss in classical musicians has been estimated at 4-43%, in rock musicians 13-30%. Statistics for the Decibel (Loudness) Comparison Chart were taken from a study by Marshall Chasin , M.Sc., Aud(C), FAAA, Centre for Human Performance & Health, Ontario, Canada. There were some conflicting readings and, in many casesNoise Output Testing. We performed four different noise output tests: Test 1: sound meter right above unit’s control panel – high fan speed. Test 2: sound meter right above unit’s control panel – low fan speed. Test 3: sound meter 10 ft. away from unit – high fan speed. Test 4: sound meter 10 ft. away from unit – low fan speed.
Decibel. The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel ( B ). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 10 1/10 (approximately 1.26) or root-power ratio of 10 1⁄20 (approximately 1. TKpL0mo.
