Noise Level Standards For Home Appliances

01/22/2011 2:19 AM

Hi Friends,

Am looking for the noise level standards for home appliances and how to measure the same using a db meter e.g At what distance from the product is the probe to be placed. What factors to be considered whilst measuring the noise / sound.

Thanks in anticipation.

Thanks. Would you by any chance be aware how the testing is done as per this standard. At what distance should the db meter be placed and the noise recorded.

A google search yielded only pay and purchase sites for this document. Would be grateful, if you have it and could share some insights into testing procedure.

thanks in anticipation.

Standard practice is to place the probe at a distance of one meter from the equipment.

Squeaky toys, toys musical instruments have a level of 140 dBA and beyound.

Home Appliances ( washing machines, electric mixers, dryers, vacuum cleaners etc.) have a noise level of up to 90 dBA.

Personal stereo system with headphones up to 112 dBA.

Garden equipment of the order of 130 dBA.

Continued exposure to noise above 85 dBA over a period of time will eventually harm hearing.

Both the level of intensity and the length of exposure (duration) is accounted for, however as a general rule thumb if you notice a buzzing or ringing sound in your ears or that speech is muffled after exposure to noise than the noise is too loud.
