Abstract
An ear-worn electronic device comprises a housing, electronic circuitry, a power source, a microphone, and a receiver or speaker. The housing comprises a nozzle dimensioned for deployment within at least a portion of an ear canal. The nozzle comprises a distal portion, a proximal portion, a cavity within the nozzle, and a terminus surface at the distal portion comprising a sound port through which sound can pass out of the nozzle. The nozzle comprises an acoustical vent arrangement comprising a proximal port provided at the proximal portion, a plurality of distal ports provided at the terminus surface, and at least a portion of the nozzle cavity in fluid communication with the proximal port and the distal ports. Each of the distal ports has a volume smaller than that of the proximal port, and a volume of the proximal port is substantially equal to that of the distal ports cumulatively.
