Accurate calculations are essential for seeking benefits and compensations.
The configuration, or shape, of the hearing loss refers to the degree and pattern of hearing loss across frequencies (tones) as illustrated in a graph called an audiogram. For example, a hearing loss that only affects the high tones would be described as a high-frequency loss.
Results: The hearing loss for numbers a(1) is calculated as a(1)=p(1)+(50-v(1)) (p(2)-p(1))/(v(2)-v(1))-18,4 for two available measured values and as a(1)=p(1)-0,13 v(1)-11,9 if only one measured value is used, with v(i )being number intelligibility in percent at the level p(i) in decibels (dB) of measurement number i.
In the simplest terms, the fitting formula determines the amount of gain that is applied based on the hearing loss programmed to the device. There are evidenced based fitting formulas that are commonly used in clinical practice with adult patients, and are the gold standard for pediatric fittings (DSLv.

Method to calculate impairment in percentage Step1: Add Air and Bone conduction thresholds at 500, 1000, 2000 and 4000 Hz (25 is lower fence and 95 is upper fence) and divide by 4. Step 2: Subtract 25 from the average number calculated in step 1 to get a balance number. Step 3: Multiply this balance number by 1.5.
