Hearing aid acoustic transducer FH/FFH series

ultra-compact

The FH receiver represents an unprecedented combination of ultra-compact size and high SPL output with efficiencies normally found only in much larger receivers. Available with Knowles' FerrofluidTM technology for reduced vibration, improved shock performance, and reduced wax-clogging problems means easier manufacturing and greater field dependability for ITC and CIC instruments. Features 124dB SPL maximum output Two-terminal zero-bias and three-terminal configurations Undamped, screen damped, internally damped, and FerrofluidTM damped responses with 2dB, 4dB, or 6dB peak amplitude Numerous port locations Wide range of coil impedances Available with FerrofluidTM technology offering screenless damping for superior shock performance and reduced receiver vibration
