Hearing levels
Hearing loss can range in severity from a mild hearing loss,
which may cause a child to only miss out on a few sounds around
them, to a more significant hearing loss, which may cause a child
to be completely unable to hear. Hearing results are plotted
on a special graph called anaudiogram.
An audiogram shows the softest sounds a person can hear at
different pitches or frequencies.
The degree of hearing loss may be classified as:
|
MILD (25-40 dB)Your child may have difficulties hearing speech
in noisy environments or when you are not directly facing them
|
|
|
MODERATE (40-70 dB)Your child may have difficulties following
speech and other relatively quiet noises
|
|
SEVERE (70-90 dB)Your child may have difficulties hearing speech
in quiet surroundings and will not hear general noises unless they
are loud
|
|
PROFOUND (90 + dB)Your child is unable to hear most sounds
unless they are really loud
