Currently, the body mass index (BMI) is most commonly used to determine adiposity. Lear, the relationship between excess adiposity and insulin resistance (and its consequences) will vary as a function of ethnicity, generating the need, as stated by Dr.
Any sound above 85 dB can cause hearing loss, and the loss is related both to the power of the sound as well as the length of exposure. You know that you are listening to an 85-dB sound if you have to raise your voice to be heard by somebody else.
40 dB sounds twice as loud as 30 dB and 8 times as loud as 10 dB (10 to 20 to 30 to 40 = 2 x 2 x 2 = 8). Normal hearing ranges from 0 to 20 dB in all frequencies. From here on, the assumption is that you have a sensorineural hearing loss (that you have nerve damage to the inner ear).Nerve damage, unless sudden, is permanent. For conductive hearing losses, see your otolaryngologist (your ENT physician).f all of the X's (for the left ear) and all of the 0's (for the right ear) fall above the line you just drew, you have normal hearing. If anything is below that 20 dB line, you have a hearing loss. Your hearing loss is classified according to how far down the graph the marks go, and in what freqencies the loss occurs.
