A silencer is disclosed with a bypass resonator (4; 9, 12) connected by at least one tubular connection (3a, 3b; 7, 8; 13) to a sound-transmitting channel (1). The tubular connection (3a, 3b) can have various lengths (La, Lb), tubular connections (7, 8) of different thicknesses can be connected, or the volume (V1, V2, Vn) of the bypass resonator (13) can be variable.
