Silencers are a very effective way to reduce two of the most severe kinds of turbocharger noises, called “pulsation” noise and “blow” noise. PSA has developed its own silencer design based on a combination of a Herschel-Quincke tube and two quarter-wave resonators. The new device has a transmission loss of over 15 dB from 1600 to 3400 Hz. It will be first applied on the 2001 Peugeot 406 and Citroën C5.
