dc.description.abstractThe present analysis reveals that the performance of an expansion chamber is greatly affected by the expansion ratio, the sound frequency and to a lesser extent the chamber length. This conclusion was verified experimentally. It is shown that plane-wave theory is valid only at low sound frequencies and small expansion ratios. It is also concluded that expansion-chamber mufflers are efficient in attenuating low-frequency sound, which make them ideal for automotive silencing applications.en_US
