WALSH, S.J., ROBINSON, I. and STIMPSON, G., 2003. Alternator tonal noise target setting. Acta Acustica united with Acustica, 89 (3), pp.451-459.
The aim of the research reported in this paper is to develop a procedure to determine target levels for the tonal
noise emitted by a vehicle alternator. The investigation begins with a study into the contribution of the alternator
to the noise inside the vehicle. This is followed by the description of an experiment to determine subjectively
threshold levels for alternator tonal noise. From the results of these tests alternator noise target levels are derived.
Finally, the derived alternator target noise levels are compared with current alternator performance.
