Hearing, taste and smell signs

​

The hearing signs may lead to learning delays in the class or lecture, and to misunderstandings at work as patients cannot follow instructions in real time.

They include:

​

Perceptual deafness characterised by inability to perceive sounds despite normal results to audiometry testing;

​

Delay in auditory perception, due to a lag time needed to process the audio information;

​

Tinnitus;

​

Hyperacusis.  

​

Alterations of taste and smell, including partial or total loss, or conversely exacerbation of taste and smell.
