title: Normal pure tone thresholds for hearing by bone conduction.
abstract: Reference equivalent thresholds on a Brüel and Kjaer artificial mastoid have been obtained from bone conduction measurements made on a group of otologically normal listeners. The results are compared with other recent work. Various methods of presenting reference thresholds are discussed. A new method for masking the non-test ear is described.
