    10:45 for meaning of the other components of the formula. 20 to 30 dB for relative masking level (RML)

    I have three more questions:
    1. In the ABR masking noise calculator, in the section " dBeHL non-test BC ABR threshold" this section do we can put both values, BC value and AC value or just only BC because in the video he said put AC value=15 dBeHL but the calculator is for dBeHL non-test BC ABR threshold?
    2. in the masking noise calculator, If we do not know the BC value or AC value in that collum, do we put it in 0 dB in the "dBeHL non-test BC ABR threshold collum"?
    3. The correct factor of 20 dBnHL is 25dBeHL for 4K CE-Chirp for age < 12 weeks but in the video is 15dBeHL put in "dBeHL non-test BC ABR threshold" collum in the masking noise calculator, why was that?

    How much dB between right ear left ear that we make a decision for masking? 50 dB interaural attenuation?

      Hi, see Rule 1 in www.interacoustics.com/academy/audiometry-training/pure-tone-audiometry/pure-tone-audiometry-introduction#cross-hearing-masking
      "Masking is needed at any frequency where the difference between the left and right not-masked air conduction thresholds is 40 dB or more when using supra- or circum-aural earphones or 55 dB or more when using insert earphones."
      Best regards,

    I understand that with infants cross cranial transmission is less, but why does IA reduce with age. I thought it should increase. Please assist
