Custom-made ear moulds offer many advantages over universal products. The advantages include:
Custom-made products offer acoustic stability.
There is little to no loss of the hearing aid’s capacity with custom-made products.
Custom-made products fit narrower ear canals so there is less likelihood of irritation and distortion of the ear canal.
Custom-made products stay in position and do not come loose in the ear canal.
Custom-made products offer an ‘open’ effect.
Ear wax is less likely to penetrate the receivers of RIC devices.
No intervals in mid-range tones.
Features such as directional microphones and noise suppression are more effective in custom-made products.
