It is very important that the measurements are not influenced by sounds or noise relating to anything else than the
presented test signals. Measurements of peak levels will be influenced by any sounds louder than the presented test
signals. Even extremely brief sounds may impact the measurements.
It is therefore important that the environment is well controlled to prevent any unforeseen influence.
