    The occlusion effect (OE) in bone conduction speech reception thresholds (SRTs) is greater with forehead placement than mastoid placement. This finding impacts how masking levels are calculated for hearing tests.

    Area of Science:

    • Audiology
    • Hearing Science
    • Speech-Language Pathology

    Background:

    • The occlusion effect (OE) is a phenomenon that can influence hearing test results.
    • Understanding OE is crucial for accurate assessment of bone conduction hearing.
    • Previous research has explored OE with various transducer placements.

    Purpose of the Study:

    • To quantify the occlusion effect for bone conduction speech reception thresholds (SRTs).
    • To compare the OE between forehead and mastoid placements for bone conduction testing.
    • To inform the calculation of effective masking levels in audiological assessments.

    Main Methods:

    • Bone conduction speech reception thresholds (SRTs) were measured in 24 normally hearing participants.
    • The occlusion effect was assessed using both forehead and mastoid transducer placements.

  • Standard audiological procedures were followed to determine SRTs and masking levels.

    • Main Results:

    • The occlusion effect (OE) was approximately 3 dB larger when using forehead placement compared to mastoid placement.
    • Intersubject variability for the OE was comparable between forehead and mastoid positions.
    • The findings suggest a need to adjust masking level formulas based on placement.

    Conclusions:

    • Forehead placement of bone conduction transducers results in a larger OE than mastoid placement.
    • The OE should be considered when determining effective masking levels for bone conduction SRTs.
    • A formula adjustment of +18 dB is suggested for OE in bone conduction masking with mastoid placement.
