The Sensorineural Acuity Level (SAL) Technique: An Experiment with Some Observations

Arch Otolaryngol. 1961;73(6):710-716. doi:10.1001/archotol.1961.00740020724017

The clinical use of conventional boneconduction audiometry has been questioned, for various reasons, almost since the beginning of its application. The many variables involved in assessing cochlear reserve by this technique have been described in detail elsewhere.1-3 Suffice it to say that the uncertainties of the technique have led some workers to suggest that conventional boneconduction audiometry may have only limited practical value.

The growing dissatisfaction with this methodology led Rainville4 to propose a new method for assessing sensorineural hearing level. An English translation of Rainville's paper is now available, and her technique has been explained elsewhere.5-6 The methodology which she employed, although ingenious, was somewhat cumbersome as a routine clinical tool. Consequently, a modification of her method which permits rapid assessment of sensorineural acuity level (SAL) in the clinical setting has been suggested.6

In the SAL technique, described by Jerger and Tillman,6 sensorineural acuity
