How to choose the right hearing aid? Please refer to the table

Calculate:

1 set: Choose a value within the range of hearing loss E.g: Select extremely severe, part 10. Choose a value 100dB

2 set: Selecting the peak gain value of the hearing aid.

E.g: The peak gain value of your hearing aid is 65dB.

set: Subtract the value in step 2 from the value in step 1. It will be he smallest decibel value can be hear after using a hearing aid.

E.g:100dB-65dB-35dB, so that the part4 to part10 sound can be hear

Part	Reference scene	Hearing loss
1	Rustling of leaves, the sound of birds(10dB)	Normal
2	Running water sound(10-20dB)
3	Whisper(15-25dB)
4	Watch walking sound(30-40dB)	Mild hearing loss
5	Daily talking sound (40-60dB)	Moderate hearing loss
6	Dog barking(Lowfrequency,60-80)	Moderate to severe hearing loss
7	Speak loudly(Distance 1-2M, 70-80dB)
8	Speak loudly( Near you, 80-100dB)
9	Phone ringtone(80-90dB)	Extremely severe
