Mild
You may have difficulty following speech, especially in noisy situations.
This type of loss is often noticed by family first rather than the patient.
Moderate
You may often have difficulty following speech and miss other quiet noises.
Amplification is very successful for this loss, but the patient also needs to
use good hearing tactics.
Moderately-severe
You would be unable to hear speech even in quiet surroundings and may
not hear general noises such as traffic unless they are loud. Amplification is
very successful for this loss, but the patient also needs to use good hearing
tactics. Lip-reading classes could benefit people with this hearing level.
Severe
You would be unable to hear most sounds unless they are very loud.
Amplification is useful, but the patient will also need to rely on good
hearing tactics.
Profound
Will need to wear appropriate amplification technology (e.g. hearing aids,
cochlear implant, FM) in order to hear conversational speech. You may
not hear traffic noise unaided. Lip-reading classes would also be useful for
people with this hearing loss. Patients in this category may also use sign
language and watch sign assisted programmes.
