There is always a ‘trade-off’ when buying a private hearing aid. The commonest choice is between size and technology. There is very little difference in the cost of similar technology between manufacturers and the restrictions based on size are generally the same.
The recent developments in digital feedback cancellation (DFC) mean that even the smallest hearing aid can deliver power without whistling (feedback). Even severe levels of hearing loss can be managed by small hearing aids.
IIC – Invisible In Canal
Single microphone devices, wireless connectivity is possible, limited output, invisible
CIC – completely in the canal
Single microphone devices, wireless technology, often invisible depending on size and output.
ITC – in the canal
The smallest device to benefit from dual microphone directionality and wireless technology. Many can accommodate Bluetooth.
ITE – in the ear
A device which fills the ear concha. Large enough to take all the latest technology with maximum power.
RIC (RITE) – Receiver in the canal
The loudspeaker of the hearing aid is placed in the ear canal and is connected to a fitting behind the ear with a very small wire. It can be made fairly invisible as the wire is hard to see and the fitting behind the ear is matched to hair colour. The other advantage is that it is less prone to whistling.
BTE – behind the ear
The whole hearing aid is fitted behind the ear and a tube leads sound into the ear canal, generally with an ear mould to hold it in place. These devices are dispensed by the NHS.
