After a brief discussion of the past use of and clinical need for high frequency hearing tests, a new technique is described that uses a special electric transduction mode: a 60-kHz carrier frequency is modulated by the desired audiofrequency. The combined signal is applied to the skin over the mastoids by Mylar-covered electrodes. On perception, the audiofrequency part of the input shows all the properties of a bone-conduction signal. The carrier frequency is dispersed in the tissues. Production and calibration of electrical high frequency signals, up to 20 kHz, is straightforward and easier than that of conventional air-conduction and (vibromechanical) bone-conduction signals. The efficacy of the method is illustrated by means of preliminary hearing tests conducted on several subjects.

Review
An audiogram is a hearing test conducted under ideal listening conditions in a soundproof booth. The test includes different pitches and intensities and the results are conveyed in graphical form. If there is hearing loss an audiogram helps distinguish conductive loss (outer/middle ear) from sensorineural loss (cochlea/cochlear nerve).

Comparative Study
Emergency departments (EDs) are a common location for patients to present with sudden hearing loss (SHL). Unfortunately, high-quality, rapid quantitative measurement of hearing loss is challenging. Herein, we aim to evaluate the accuracy of tablet-based audiometry in patients complaining of SHL. Prospective tablet-based testing was completed in the ED in patients complaining of SHL. Air conduction thresholds (ACTs) obtained via tablet-based audiometry were compared to same-day measurements with a clinical-grade audiometer. Hearing loss (HL) was defined as >20 dB ACT for any frequency. In participant-level analysis, 30+ dB HL in 3 consecutive frequencies was used to define SHL. In the ED, mobile audiogram ACTs were within 5 dB (77%) and 10 dB (89.6%) of those determined by conventional audiometry. The sensitivity and specificity for mobile audiometry to detect 3 or more consecutive thresholds with 30+ dB HL were 100% and 62.5%, respectively. Findings have implications for increasing access to high-quality audiometry.

The selection of appropriate hearing test procedures is dependent upon the goals chosen by the practitioner and the skills of the examiner. Office audiometry is superior to tuning-fork tests and provides unique information for diagnosis and management.
