Hearing aids are small electronic devices designed to improve hearing for individuals with hearing loss. Worn in or behind the ear, they amplify sound to make speech and other noises clearer. Modern hearing aids come with advanced features like noise reduction, Bluetooth connectivity, and rechargeable batteries, making them more convenient and efficient. There are various styles available, including behind-the-ear (BTE), in-the-ear (ITE), and completely-in-canal (CIC) models, catering to different needs and preferences. Hearing aids significantly enhance the quality of life by improving communication, reducing the effects of hearing loss, and helping people stay engaged in daily activities.
