Speech Audiometry - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/medicine-and-dentistry/speech-audiometry
Speech audiometry assesses auditory discrimination as opposed to auditory acuity, requiring the subject to repeat standard word lists delivered through headphones at varying intensities. The responses are scored to provide an assessment of auditory discrimination that, together with other tests, is valuable in distinguishing conductive from sensorineural hearing impairment (in …
Predicting Speech Discrimination from the Audiometric ...
https://pubs.asha.org/doi/10.1044/jshr.2304.814
To develop a method for predicting a speech discrimination score (SDS) from audiometric thresholds (SRT and pure-tones) three prediction systems were investigated: a stepwise multiple regression procedure, smear-and-sweep analysis and a …

Some patients may have exceptionally poor speech discrimination despite near normal pure tone audiometry. Speech discrimination scores in a series of 425 cases of acoustic neurinoma were 0% in 35% of patients, very poor (2–30% discrimination score) in 21%, moderate to poor (32–60% discrimination) in 16%, and moderate to good (62–100%) in the remaining 28% of cases …

The speech discrimination score is obtained using phonetically balanced, one-syllable words usually presented at 25 to 40 dB above the hearing threshold obtained from the pure-tone audiogram. Speech discrimination is usually good in purely conductive hearing losses when the presentation level is loud enough.

A pure tone audiometry test measures the least audible sound that a person can hear, whereas the speech discrimination test asseses the veteran’s ability to understand speech from background noise. If a veteran’s speech discrimination is poor, the …
Speech discrimination in the sensorineural hearing loss ...
https://pubmed.ncbi.nlm.nih.gov/9753995/
Abstract. There are patients who have normal hearing below 3,000 Hz and normal speech discrimination who still complain of hearing difficulty, especially when background noise is present. The objective of this study is to document the fact that these individuals have a significant hearing impairment that is not detected with routine testing.

Audiometric Speech Discrimination. Upon failing both conversational voice and pure tone audiometric test, an audiometric speech discrimination test should be administered (usually by an otologist or audiologist). The applicant must score at least 70 percent at an intensity no greater than 65 Db in either ear. Equipment. Approval.
Acoustic neuroma: deterioration of speech discrimination ...
https://pubmed.ncbi.nlm.nih.gov/11039874/
Pure-tone and speech audiometry were performed in 231 patients with a unilateral acoustic neuroma. Tumor sizes were obtained through imaging. Audiometric parameters, such as the mean pure-tone thresholds, the maximum discrimination, the slope of the speech audiogram, the roll-over index and the difference between the speech reception threshold and the Fletcher …
