Auditory imagery is the experience of “hearing” sounds in your mind without any external sound being present. When you imagine a friend’s voice, replay a song in your head, or mentally rehearse what you’re going to say before speaking, you’re using auditory imagery. It can feel remarkably vivid, sometimes almost as lifelike as actually hearing the sound, and it’s one of the most common forms of mental imagery humans experience.
How Auditory Imagery Works in the Brain
The most striking thing about imagining a sound is that your brain treats it a lot like hearing a real one. Brain imaging studies consistently show that auditory imagery activates many of the same neural networks that respond when you actually hear something. The auditory cortex, the part of the brain that processes incoming sound, lights up even when you’re just imagining music or a voice in silence.
But auditory imagery isn’t just an auditory cortex phenomenon. The supplementary motor area (a region involved in planning movement), the parietal cortex, and parts of the frontal lobe all play a role. This motor system involvement makes intuitive sense: when you imagine singing a song, your brain partially simulates the physical act of producing that sound. Research published in Cerebral Cortex found that people who have more gray matter volume in these motor-planning regions report more vivid auditory imagery. The same study showed that people whose brains make sharper neural distinctions between different sounds when listening also tend to experience richer mental sound images.
Voluntary Versus Involuntary Imagery
Auditory imagery comes in two broad forms. Voluntary auditory imagery is the deliberate kind: you choose to replay a melody, imagine how a sentence sounds in someone else’s voice, or mentally rehearse a musical passage. You control when it starts and stops.
Involuntary auditory imagery is the kind that shows up uninvited. The most familiar example is the earworm, a fragment of music that loops in your head for minutes or hours without your choosing it. A survey of 883 people found that earworm frequency is closely linked to general habitual tendencies in everyday life. People who are more prone to repetitive behaviors, like foot tapping, counting, or spelling words mentally, tend to get earworms more often. This suggests earworms aren’t random glitches but arise from the same brain systems that produce and regulate habits. The association holds even after controlling for anxiety, pointing to a neurocognitive pattern rather than a stress response.
Auditory Imagery Compared to Visual Imagery
Most people assume visual imagery is the dominant sense in the mind’s eye, but research tells a different story. A study examining mental imagery across multiple senses found that auditory mental images were superior to visual ones on almost every measure tested, except for spatial properties. Auditory imagery starts faster, forms more readily, lasts longer, and remains more consistent over time. In other words, your mental ear may be more reliable than your mind’s eye for most people, even if visual imagery gets more attention in popular culture.
Your Inner Voice Is Auditory Imagery
The internal monologue most people experience throughout their day is a specific form of auditory imagery. When you think in words, silently narrate your actions, or mentally compose a text message before typing it, you’re generating auditory images of speech. This “inner voice” relies on the same brain regions that process external voices, particularly the supplementary motor area and auditory cortex working in tandem. The two main domains of auditory imagery that researchers study are voices and music, which together account for the vast majority of what people “hear” internally.
Recent debate in psychology has centered on whether some people truly lack inner speech entirely. A 2024 study coined the term “anendophasia” for the supposed absence of an inner voice, but a commentary in Psychological Science noted that the original study never actually confirmed a single participant with a complete absence of inner speech. The participants who scored lowest on inner speech questionnaires performed worse on verbal working memory tasks and were slower at making rhyme judgments, but whether they had zero inner speech or simply less remains an open question.
When Auditory Imagery Is Absent
Just as some people lack visual mental imagery (a condition called aphantasia), some people report little or no ability to hear sounds in their mind. Researchers have proposed the term “anauralia” for this experience. In one study of 128 participants, 29 were categorized as anauralic. Of those, 25 reported the absolute minimum score on every item of a standardized auditory imagery questionnaire, indicating they experienced no mental sound at all when asked to imagine things like a ringing telephone or a familiar voice.
Anauralia and aphantasia overlap but aren’t identical. You can have vivid visual imagery but a silent inner world, or vice versa. The relationship between these conditions is still being mapped out, and researchers acknowledge that self-report measures for both need further validation. If you’ve ever wondered why you can’t “hear” a song in your head while others seem to replay music effortlessly, anauralia may describe your experience.
How Vividness Is Measured
The standard tool for assessing auditory imagery is the Bucknell Auditory Imagery Scale, or BAIS. It’s a questionnaire with two subscales: one measuring vividness (how clear and lifelike your mental sounds are) and one measuring control (how well you can manipulate those sounds, like changing the tempo of an imagined song or switching between voices). Each subscale has 14 items rated on a 7-point scale. Higher scores on vividness mean your internal sounds feel more real; higher scores on control mean you can shape and direct them more easily.
These two dimensions don’t always go hand in hand. Someone might experience extremely vivid auditory images but struggle to change or direct them, while another person might have moderate vividness but excellent control. This distinction turns out to matter for real-world skills.
Practical Effects on Performance
Auditory imagery isn’t just a quirky feature of consciousness. It has measurable effects on how people perform in tasks that require timing and coordination. Research on sensorimotor synchronization (the ability to move in time with music, like tapping along to a beat) found that imagery vividness and control make distinct contributions. Vividness helps people perceive the timing of expressive, naturally played music, while control helps them actually synchronize their movements with irregular rhythms. Working memory, meanwhile, helps people anticipate upcoming beats in a sequence rather than just reacting to them.
This has practical implications for musicians, dancers, athletes, and anyone whose work involves rhythmic coordination. Mental rehearsal of sounds, essentially practicing through auditory imagery, activates the same motor-planning circuits that physical practice does. This is why musicians often report that imagining a piece of music can genuinely improve their performance of it, even without touching their instrument.
