auditory late responses (ALR)

Auditory late responses (ALR) are brain signals that occur a short time after we hear a sound, reflecting how the brain processes and interprets auditory information. They are measured using specialized tests that record brain activity, helping clinicians understand how well the brain is processing sounds like speech and noise. ALRs typically occur a few hundred milliseconds after a sound and are used to evaluate hearing, brain function, or a person’s ability to understand auditory input, especially in individuals with hearing impairments or neurological concerns.
