What term describes mental representations of sounds or auditory stimuli?

The correct term for mental representations of sounds or auditory stimuli is acoustic images. Acoustic images refer to the way individuals mentally store and recall auditory information. This concept encompasses various forms of sounds, including music, speech, and environmental noises, and highlights the brain's ability to create vivid recollections of auditory experiences.

The other terms relate to sound and memory but do not specifically describe the mental representations of auditory stimuli in the same way. For instance, echoes are reflections of sound that can be heard after the original sound is produced, while auditory memory pertains to the ability to remember sounds over time, which is a broader concept. Sounds, in general, do not capture the mental aspect of how these auditory stimuli are represented or stored in the mind. Understanding acoustic images allows for greater insight into how we process and recall the sounds we hear in our environment.
