Hearing Aids are not sold today on trial basis. The scientific way is to first know the condition of the ear, the extent of hearing loss, more importantly, the frequencies to which the patient responds or does not
	respond. At C C SAHA LTD., we have over the years imported and used the very latest Audiological Instruments to ascertain the nature and extent of hearing loss. This enables an ENT DOCTOR to prescribe the correct type of hearing aid, which we can dispense from our huge and comprehensive stock.

Programmable Hearing Aid:
The word 'programmable' or 'digital' as a prefix to hearing aids is now widely used. To explain the programmable hearing aid, one has to consider the audiogram report of the patient. The graph has the audio frequency and the gain (in dB) as the two parameters. This graph is used to tune or program a programmable or digital hearing aid. These hearing aids have special trimmers, which can be tuned to boost only those frequencies in which the patient is deficient. This enables the patient to hear as close to normal hearing as possible.

^ Hearing Aid Programming / Dispensing

Programmable hearing aids are dispensed in the form of the BTE (behind the ear), ITE (in the ear), ITC (in the canal), or CIC (completely in the canal). Wearing these hearing aids, a person will not have to hear the amplified sounds of the frequencies he is already hearing well. Only those frequencies where he is deficient will be boosted or amplified for his comfort and ultimate listening pleasure. Naturally these hearing aids are more costly than the conventional hearing aids, but more people are opting to spend the extra money get an instrument which is aspiring for technical perfection.
