Hearing aids, known as heyrnartæki in Icelandic, are electronic devices designed to amplify sound for individuals with hearing loss. They are typically worn in or behind the ear. The primary function of a hearing aid is to make sounds louder and clearer, thereby improving communication and the ability to perceive environmental sounds.

Modern hearing aids consist of several key components: a microphone to pick up sound, an amplifier to increase the sound's volume, and a speaker (receiver) that delivers the amplified sound into the ear canal. Many also include a battery for power and a telecoil option that allows for direct connection to telephone receivers or loop systems.

Hearing aids are available in various styles and sizes, catering to different levels of hearing loss and personal preferences. These include behind-the-ear (BTE), receiver-in-canal (RIC), in-the-ear (ITE), and completely-in-canal (CIC) models, among others. The selection of a hearing aid is usually made in consultation with an audiologist, who can assess the individual's hearing loss and recommend the most suitable device.

The effectiveness of hearing aids can vary. While they significantly benefit many users, they do not restore normal hearing. They help to manage hearing loss by amplifying sounds, but the clarity of the amplified sound depends on the nature and degree of the hearing impairment, as well as the specific features of the hearing aid. Regular use and proper adjustment are crucial for optimal results.
