This finding is thought to support the notion that the audiologist may use warble tone with stimulus parameters up to and including frequency deviations of +/- 5% with modulation rates of five per second to measure thresholds, which are directly comparable to pure-tone thresholds for patients with normal hearing and. Frequency-modulated tones that can be used to overcome the problems that occur with pure tones in the *sound field. 3 Apr - 3 min - Uploaded by Telco Steve This is a Warble Tone unit that was manufactured by Floyd Bell Inc. Here I show the unit hooked.
Download citation | Warble Tone as an Au | Pure-tone and warble-tone thresholds were compared for normal-hearing inexperienced adult listeners at six. 21 Jan Pure-tone, warble-tone, and narrow-band noise thresholds were compared in terms of sensitivity and clinical test-retest reliability. Test-retest reliability of sound field audiometry has been evaluated by means of repeated determinations of hearing threshold levels for frequency-modulated.
Walker, Dillon, and Byrne () suggested reference equivalent threshold sound pressure levels (RETSPLs) for warble tones with specific modulation. Pure tone audiometry (PTA) is the key hearing test used to identify hearing threshold levels of Therefore, it may be necessary to use other stimuli, such as warble tones in sound field testing. There are variations of conventional audiometry. Using warble tones to reduce the effect of standing waves and utilizing a design of multiple crossings of the auditory threshold, a reliable audiometer test was.
