1. Select initial amount of masking for the non-test ear (i.e., air-conducted threshold of the non-test ear (AC Nontest + 10 dB HL), plus correction factor for occlusion effect, if applicable ; 2. Re-establish threshold in the test ear with this initial amount of masking (e.g., AC Nontest Ear+10); 3.

Bone conduction pure tone audiometry In bone conduction pure tone audiometry masking for bone conduction assessment is required when there is a gap at any frequency of 15dB or more between the unmasked bone conduction result and the air conduction threshold. This is known as the air-bone gap. Masking in bone conduction testing

Defining Effective Masking EM definition – if masking noise of that level is in the ear, and the tone is put into the same ear at equal in intensity, you have masked. E.g. 50 dB EM masks 50 dB PT in SAME ear. So, if crossed over… if the tone crosses over at 10 dB HL, theoretically, putting in 10 dB E…

The audiogram is the chart on which hearing ability is recorded and shows the threshold hearing level (in dB HL) against the frequency (in Hz). There are 4 audiometric descriptors to describe hearing loss: mild (20-40 dB), moderate (41-70 dB), severe (71-95 dB) and profound (>95 dB).

Two-lines are plotted on audiogram chart. One has a blue color with x letter and another is the red color with the O letter scheme. The blue color indicates, as the result of the left ear hearing test conduct. And the red color is for the indication of the right ear test result. The letters are showing the levels of hearing at each pitch. Key :

An audiogram is set up as a chart with the horizontal X-axis representing frequencies, or Hertz (Hz). 1 The X-axis is divided into two parts: On the left side of the "divide" are the low frequencies. On the right side of the "divide" are the high frequencies . The vertical Y-axis represents decibels. 1 Decibels represent the hearing level, or how loud it is.
