G82 – Control the background noise.

Standard

Guideline:

Control the background noise.

Guideline Description:

Background noise affects the hearing of the older adults. Due to this factor, the background  noise should be controlled in order to promote a better hearing,using a mechanism of adjustment in the interface and selecting a quiet environment place for testing.

Example:

exemplo G82

G77 – Increase duration of sound signals.

Standard

Guideline:

Increase duration of sound signals.

Guideline Description:

To face the limitations of auditory capabilities of older adults it is important increasing sound duration for a better hearing. For example, in the case of use of a signal sound with high frequency (>2000 Hz), use longer duration (>0.5 s).

Example:

G76 – Allow users to replay auditory messages.

Standard

Guideline:

Allow users to replay auditory messages.

Guideline Description:

Decreasing of auditory capabilities in the older adults is common. This factor can affect the comprehension of speech. This limitation can be overcome through of the repetition of audio messages.
