Acoustic “Barrier-Free” state is quite important for people suffering from hearing impairment for maintaining their quality of life.
Poor speech discrimination leads to poor speech communication.
Here, in this paper, the barrier-free state for hearing impaired people, especially, those with senile deterioration of the hearing acuity with poor speech discrimination is discussed.
Hearing aids, cochlear implants, etc., are strong tools in respect of a medically oriented approach to preventing removing the barrier against people suffering from hearing impairment.
It is not the aim of this paper to discuss these medical equipments, but the so-called “assistive products” which are thought to be effective as a more sophisticated way towards achieving the barrier-free state for people with moderate hearing impairment.
Our objective is to understand updated information about the assistive products and provide adequate advice to these patients to achieve better speech communication.
