Abstract
Disclosed is a mute that attaches over the bell of a wind instrument which can be used for practice or performance. The shell of this mute consists of a symmetrically shaped cylindrical plastic jar. Attached to the exterior of the mute shell is an illuminated ON-OFF switch that is connected to a 12 VDC blower fan motor and a 12 V AC adapter. The 12 VDC blower motor inlet is attached to a plastic inlet duct contained in the mute shell. The blower motor vent is attached to a plastic egress duct which exits the mute shell. The ventilation system is encompassed by acoustical foam. This mute muffles the sound of a wind instrument without altering its pitch or timbre, and without creating any additional pressure at the players lips.
