Sound Sensitivity

· Introduction

· Hyperacusis

· Hyperacute Hearing

· Phonophobia

· Recruitment

Introduction

" There are four different conditions that all can have similar

characteristics--normal sounds are TOO LOUD to stand. Sometimes it can be

difficult to tell these conditions apart, namely: 1. hyperacute hearing,

2. hyperacusis, 3. recruitment and 4. phonophobia. "

Hyperacusis/Recruitment

" …Individuals who have collapsed tolerance to sound. This unique

international community consists of individuals with hyperacusis,

recruitment, hyperacute hearing, Meniere's disease, and even autistic

children. "

Hyperacute Hearing

" These individuals represent a larger group of sound sensitive individuals

in the world. To the best of our knowledge, they are usually born sound

sensitive and do not have tinnitus. This group shares two similarities to

people with hyperacusis: they usually have no hearing loss; and share the

ability, like hyperacusis patients, to produce an audiogram showing hearing

sensitivity at negative decibel levels. "

Hyperacusis Network: Supplement

" This is a rare condition where a person can hear certain sounds at a much

softer volume than a person with normal hearing. Therefore, if these sounds

are even of moderate loudness, they can seem very loud if you have

hyperacute hearing at that frequency. "

Hyperacusis/Recruitment

Phonophobia

" This is a mental condition where people become or are afraid of certain

sounds that they associate with " bad things " . As a result, they perceive

these sounds as much louder than they really are. "

Hyperacusis/Recruitment

Recruitment

" This, I believe, is the largest group of sound sensitive people in the

world. In lay terms, recruitment is similar to having hyperacusis, but with

the added feature of hearing loss. Usually this group consists of

individuals over 40 years of age that have the classic high frequency

hearing loss evident on their nose diving audiogram. "

Hyperacusis Network: Supplement

This condition is ALWAYS a by-product of a sensorineural hearing loss. (If

you don't have a hearing loss, you can't have recruitment.) A person with

recruitment perceives volume increases much faster than the actual volume

increase. As a result, sounds rapidly become too loud to stand. A hard of

hearing person may have both recruitment and hyperacusis at the same time.
