The iPhone uHear PTAs in all three settings were compared with the formal audiogram PTAs, where the PTA is calculated as a mean of thresholds (hearing in dB) at 500, 1 000, 2 000 and 4 000 Hz.
Data are collected in SPL and converted to show conventional frequency thresholds in decibels hearing level (HL) in order to be consistent with a typical clinical audiogram.
Therefore, a need for initial site evaluations and for baseline hearing assessments has been established, as well as the need for annual audiograms to evaluate for standard threshold shift.
She converted very quickly to negative sputums (within two weeks) and it was fairly localised--but after two and a half months her audiograms deteriorated while she subjectively noted that her hearing was worsening,' he explained.
Air-conduction audiograms with 3,000, 4,000, and/or 6,000 Hz thresholds at higher hearing levels (HLs) than the adjacent 2,000 and 8,000 Hz thresholds are historically referred to as "notched audiograms.
The inspections will be conducted over the next 12 months and include a review of medical files for occupational and non-occupational cases for 2007 and 2008, including 301 forms, worker's compensation forms, absentee reports and audiograms for a selected sample of employees.
Serial audiograms revealed that the subject's only functional (right) ear had recently developed a severe hearing loss.
Of the 37 visits, audiograms were noted in the examination of 35 (94.
Ototoxicity is diagnosed by comparing an initial audiogram--ideally obtained before initiation of ototoxic drugs--with hearing thresholds using serial audiograms, particularly ultra-high frequency thresholds.
TSS does other things in the testing arena, such as audiograms, spirometry (measuring breath), insurance exams, health fairs and safety training.
