“…These pitfalls might be avoided if a suitable unexposed reference group is selected . Recently, Robinson proposed that it is not generally realistic to compare measured hearin g loss with an " otologically normal" base line from an age-matched group, since differences between a normal and a noise-exposed population will include adventitious hearing loss along with the noiserelated components (45). Since the mean ages of our groups differed, the selection of the model affected the age correction and , further, the hearing threshold level.…”

MSc,' Ilmari Pyykko, MD2 STARCK J, PEKKARINEN J, PYYKKO 1. Impulse noise and hand-arm vibration in relation to sensory neural hearing loss. Scand J Work Environ Health 14 (1988) 265-271. The present study was carried out to determine whether impulse noise and simultaneous exposure to noise and vibration can aggravate sensory neural hearing loss (SNHL) among forest (N = 199) and shipyard (N = 171) workers. The average level of exposure to noise outside the used earmuffs and the average exposure over time were nearly equal for the two groups. The impulsiveness of the noise and the average exposure level inside the earmuffs were measured with a miniature microphone. The hearing threshold of the workers was measured at 4 kHz and then estimated according to Robinson's model to compare the observed and expected hearing loss. The impulsiveness ofthe noise was greater both outside and inside the earmuffs in shipyard work than in forest work. The average SNHL was higher than predicted for the shipyard workers and about the same as predicted for the forest workers. The total exposure level inside the earmuffs was influenced by the total wearing time. The low frequencies of the chain-saw noise were not attenuated sufficiently by the earmuffs to protect the workers' hearing. The present study suggests that exposure to impulse noise increases the risk of SNHL, but that simultaneous exposure to hand-arm vibration and noise does not.

“…The report also briefly summarized the absence of any evidence of serious side effects, including clinically marked hearing loss and nephrotoxicity, in either treatment arm. Within the study protocol, hearing loss was defined in terms of a loss that would be evident clinically and was defined as a consistent elevation of any two pure tone audiometry (PTA) thresholds above 20 dB hearing level (HL) over 2 to 8 kHz (16,22).…”

We undertook assessment of hearing in patients with cystic fibrosis who were taking part in a large randomized controlled trial of once-versus three-times-daily tobramycin for pulmonary exacerbations of cystic fibrosis (the TOPIC study). All patients were eligible to have standard pure tone audiometry performed across the frequency range of 0.25 to 8 kHz. High-frequency pure tone audiometry over 10 to 16 kHz was also performed with a subset of patients. Audiometry was undertaken at the start of tobramycin treatment, at the end of a 14-day course of treatment, and at follow-up 6 to 8 weeks later. We enrolled 244 patients, of whom 219 (125 children and 94 adults) completed treatment. Nineteen patients were excluded from analysis due to abnormal baseline audiometry. Complete pre-and posttreatment standard audiological data were obtained for 168/219 patients. We found no significant differences in hearing thresholds when they were assessed at the baseline, at the end of treatment, and at follow-up 6 to 8 weeks later were compared. In addition, no significant differences in hearing thresholds were detected between treatment regimens. Similar results were obtained for the subset of 63/168 patients who underwent high-frequency audiometry. We conclude that for a single 14-day course of tobramycin treatment in patients with cystic fibrosis with no preexisiting auditory deficit, no measurable effect on hearing was apparent with either once-or three-times-daily treatment. Estimation of the cumulative cochleotoxic risk in cystic fibrosis patients due to repeated aminoglycoside therapy, as evidenced by the patients excluded from this study due to hearing loss, also requires further characterization.

“…The mild high frequency hearing loss in both families is common in the general population (Robinson, 1988) and would not account for the abnormality of ABRs. The loss of middle ear muscle reflexes in five members of NFL + AN is typical of AN (Starr et al, 1996).…”
