Interaural attenuation characteristics for air conduction, bone conduction, and speech reception were evaluated through standard clinical audiometry techniques in 256 patients with complete unilateral sensori‐neural hearing loss. Data indicated that differences between ears of about 40 db for air conduction require the use of masking to test the poorer ear. Negative or 0 db interaural attenuation characteristics indicate the general requirement for masking in most tests of bone conduction. Lack of appropriate shadow responses may be indicative of functional involvement.
