Echoic memory is extremely common and nearly universal, as it is the normal sensory memory system for sound.

Does everyone have echoic memory?

While echoic memory is very short, it helps keep information in your brain even after the sound has ended. Though we all have echoic memory, factors like age and neurological disorders can affect how well you recall sounds. It's also normal for memory to decline with age.

Is echoic memory accurate?

Another study tested several subjects on the duration of echoic memory. Their study found one subject that was able to test with perfect accuracy up to 9 seconds after the auditory stimuli ended. This is considered exceptional, and not the rule of thumb.
