What is the purpose of compression in hearing aids?

The purpose of compression in hearing aids is to equalize sound levels for different inputs. This means that compression technology adjusts the amplification of sounds based on their intensity. For quieter sounds, the hearing aid provides more amplification, ensuring that the wearer can hear faint sounds clearly. Conversely, for louder sounds, the hearing aid reduces amplification to prevent discomfort and protect the hearing from potential damage. By doing this, compression helps to maintain a balanced auditory experience, making sounds more accessible without overwhelming the user.

This approach caters to the varying nature of sounds in everyday environments, promoting clarity and comfort for the user. Thus, it plays a crucial role in improving speech understanding in noisy situations and enhancing overall quality of life for those with hearing loss.
