What are Maxum Hearing Aids?

The Maxum system is an electromagnetic partially implanted, middle ear hearing device. The Maxum system consists of a permanent ossicular implant magnet and an external digital sound processor that is worn in the external ear.


The Maxum IPC system with a digital processor consists of a permanent ossicular implant magnet and an Integrated Processor and Coil (IPC). The IPC houses an electromagnetic coil and an external sound processor.

The sound processor in the IPC receives sound, amplifies it, and sends electrical signals to the coil at the tip of the device. This coil changes the sounds to electromagnetic signals, which cause the implant to vibrate. These vibrations travel through the cochlea, stimulating the hair cells and nerves that send impulses to the brain that are interpreted as speech or sounds.

Who can receive Maxum Hearing Systems?

The Maxum systems are indicated for use in adults, 18 years of age or older, who have a moderate to severe sensorineural hearing loss and desire an alternative to an acoustic hearing aid. Prior to receiving the device, it is recommended that an individual have experience with appropriately fit hearing aids.


The Maxum systems are contraindicated for individuals who have: conductive hearing loss, retrocochlear or central auditory disorder, active middle ear infections, tympanic membrane perforations associated with recurrent middle ear infections, or disabling tinnitus.
