Directed listening device

Definition

A mains electricity (AC-powered) audio device intended to improve the listening experience of a person who has difficulty hearing or who is hearing impaired by creating ultrasound-directed sound waves targeted at the individual without the need for earphones or headphones. It consists of an amplifier and specialized emitters (speakers) which are connected to an audio source (e.g., television, CD player); the speakers emit an ultrasonic beam with sound waves reproduced within the beam directed at the user. It is intended to be used with or without a hearing aid and operating parameters may be configured for the individual.
