- Moderate, 55 – 70 db, usually referenced with the type of hearing aids ITE (In the Ear) or type of mini-BTE (Behind the Ear).
- Heavy, 70 – 90 db, referenced to the type of pocket or super power BTE.
- Very heavy, over 90 db, referenced to the super power BTE.
With more advanced technology, hearing aids are also experiencing growth. One is in terms of practicality. Now hearing aids are available in various sizes, from the smallest size 1 X 1.5 cm to largest 7 X 5 cm. In addition, the sensitivity of hearing aids also varies, and the more sensitive will certainly be more expensive.
Viewed from technology, hearing aids consist of digital and analog. Digital can be subdivided into three categories, namely digital manual (by means of manual settings), digitally programmable (set by the computer) and digital intelligent (can adjust automatically as the workings of the ear). Even now there are hearing aids with Bluetooth. So the user can connect hearing aids with handphone to listen to music or receive telephone.
