What do deaf people hear?
Quick Answer
It depends on the degree of hearing loss: many deaf people hear some sounds, such as loud or low-pitched noises, while people with profound deafness may hear little or nothing. Silence is rarely complete. Many deaf people experience tinnitus (ringing or buzzing), and nearly all can feel strong vibrations. People born profoundly deaf often think in sign language, images or a felt sense of words rather than an "inner voice".
Key Takeaways
- "Deaf" covers a range from severe to complete hearing loss
- Many deaf people hear low-pitched or very loud sounds
- Speech may be audible but too unclear to understand
- Tinnitus means some deaf people never experience true silence
- Vibrations are felt through the body, which is how many deaf people enjoy music
- People born deaf may think in sign language or visual images
Degrees of Hearing Loss
Hearing is measured in decibels (dB) of hearing level: the quietest sound a person can detect. The World Health Organization uses these grades (better ear):
| Grade | Hearing threshold | What it is like |
|---|---|---|
| Mild | 20 to less than 35 dB | Hard to follow quiet speech or conversation in noise |
| Moderate | 35 to less than 50 dB | Normal conversation is difficult to hear |
| Moderately severe | 50 to less than 65 dB | Most conversational speech is missed |
| Severe | 65 to less than 80 dB | Only loud speech or sounds are heard |
| Profound | 80 to less than 95 dB | Only very loud sounds may be heard or felt |
| Complete / total | 95 dB or more | Little or no sound is perceived |
People with severe to profound loss are usually described as deaf; people with milder loss as hard of hearing. Many people who are culturally Deaf (capital D) use a sign language as their main language regardless of how much they can hear.
What Deaf People Actually Hear
- Low-pitched sounds: many types of hearing loss affect high frequencies most, so thunder, bass, engines or slamming doors may still be heard
- Muffled or distorted speech: voices may be audible but consonants like s, f and th disappear, making words impossible to separate
- Tinnitus: ringing, hissing or buzzing generated by the auditory system itself, common with hearing loss
- Nothing: people with complete deafness may hear no sound at all
Feeling Sound Through Vibration
Strong sound waves are physical vibrations, and the body can feel them through floors, furniture, instruments and the chest. Many deaf people enjoy music this way, and some dance clubs and concerts add vibrating floors or wearable devices. Percussionist Evelyn Glennie, who is profoundly deaf, has written about "hearing" music through her body.
Do Deaf People Have an Inner Voice?
People who lost hearing after learning spoken language often keep a voice-like inner monologue. People born profoundly deaf who grew up with a sign language commonly describe thinking in signs, seeing hands or words, or simply thinking in concepts. Those who learned to speak and lip-read may "feel" words as mouth movements. There is no single answer: inner speech follows the language a person knows best.
Hearing Aids and Cochlear Implants
Hearing aids amplify sound and help many people with mild to severe loss. Cochlear implants bypass damaged hair cells and stimulate the auditory nerve directly; they can give profoundly deaf people access to sound, though it is different from typical hearing and takes training to interpret. Using them is a personal choice, and many Deaf people live full lives without them.
Frequently Asked Questions
Do deaf people hear complete silence?
Some do, but many do not. Partial hearing, low-frequency sounds and tinnitus mean that true silence is less common than people assume.
Can deaf people hear music?
Many can hear parts of it, especially bass, and almost all can feel its vibrations. Deaf musicians and dancers use vibration and visual cues to keep time.
Do deaf people dream in sign language?
People who use sign language often report signing, or seeing others sign, in their dreams, much as hearing people dream in their spoken language.
What is the difference between deaf and Deaf?
Lowercase "deaf" describes the hearing loss itself. Capitalized "Deaf" refers to people who identify with Deaf culture and a sign language community.
Can deaf people talk?
Many can. Being deaf affects hearing, not the voice. Whether a deaf person speaks depends on when they lost their hearing, their education and personal preference.
