Abstract
Content
The following describes a structure-borne noise measuring technology that is successful as an acoustical quality control for serial test.
There are 2 examples for very efficient applications:
  1. 1.0
    Already in 1981 the first full automatically working test decices have been installed. Since then more than 30 million step wheels for car gears were tested by this procedure.
    The rolling noise is judged by limit values with exact adjustable conditions.
  2. 2.0
    The first “selfteaching”, computer-controlled electronics for electrical motors is working till today. Since 1985 the electrical and acoustical values of more than 10 million fans are tested automatically, whereby the tact rate per 2 fans amounts to 10 s.
