Levels of Music Played by Caucasian and Filipino Musicians with and without Conventional and Musicians' Earplugs.

Background: Some musicians may play the music louder while using earplugs thus reducing the effectiveness of the hearing protection offered by earplugs. In addition, the dynamic range (DR) of the music may be altered because of the use of earplugs with negative impact on perceived quality of music. There are some cultural differences in attitudes toward loudness, which may lead to differences in the loudness of music played by musicians from different cultures.

Prevalence of Auditory Problems in Children With Feeding and Swallowing Disorders.

Purpose: Although an interdisciplinary approach is recommended for assessment and management of feeding or swallowing difficulties, audiologists are not always included in the interdisciplinary team. The purpose of this study is to report the prevalence of middle ear and hearing problems in children with feeding and swallowing disorders and to compare this prevalence with that in typical children.

Method: A total of 103 children were included in the study: 44 children with feeding and swallowing disorders and 59 children without any such disorders.

Detection of auditory signals in quiet and noisy backgrounds while performing a visuo-spatial task.

Context: The ability to detect important auditory signals while performing visual tasks may be further compounded by background chatter. Thus, it is important to know how task performance may interact with background chatter to hinder signal detection.

Aim: To examine any interactive effects of speech spectrum noise and task performance on the ability to detect signals.

Emerging technologies with potential for objectively evaluating speech recognition skills.

Work-related exposure to noise and other ototoxins can cause damage to the cochlea, synapses between the inner hair cells, the auditory nerve fibers, and higher auditory pathways, leading to difficulties in recognizing speech. Procedures designed to determine speech recognition scores (SRS) in an objective manner can be helpful in disability compensation cases where the worker claims to have poor speech perception due to exposure to noise or ototoxins. Such measures can also be helpful in determining SRS in individuals who cannot provide reliable responses to speech stimuli, including patients with Alzheimer's disease, traumatic brain injuries, and infants with and without hearing loss.

Auditory sensitivity in opiate addicts with and without a history of noise exposure.

Several case reports suggest that some individuals are susceptible to hearing loss from opioids. A combination of noise and opium exposure is possible in either occupational setting such as military service or recreational settings. According to the Drug Enforcement Agency of the U.

Perception of hearing status, communication, and hearing aids among socially active older individuals.

Objective: This study evaluated the accuracy of the self-perception of auditory status among socially active older non-hearing aid users. Their perception of their own communication proficiency and hearing aids was also assessed.

Methods: Thirty participants were asked if they thought they had hearing loss, and their auditory sensitivity was determined.

Auditory lifestyles and beliefs related to hearing loss among college students in the USA.

The purpose of this study was to evaluate the auditory life styles and beliefs of college students with reference to exposure to loud sounds in the context of the health belief model. A survey was administered to 238 (40 men, 198 women) students in the USA. Results suggest that 44% of the students use noisy equipment without ear protection and 29% (69/238) of the students work in noisy environments.

Middle ear admittance and hearing abnormalities in individuals with osteoarthritis.

In osteoarthritis, the joint cartilage breaks down. Cartilage exists within the incudomalleolar and incudostapedial joints. In addition, the cartilage-covered base of the stapes footplate is bound to the cartilage-covered rim of the oval window by the annular ligament.

Prevalence of hearing loss in Rett syndrome.

This study examined the auditory status of females with Rett syndrome (RS) using auditory brainstem response (ABR) testing and measures of acoustic admittance. Prevalence of hearing impairment in 81 female patients (age range 1 year 3 months to 39 years 8 months; mean age 8 years 7 months, SD 6 years 4 months) was evaluated with ABR measurements. If the ABR latencies at 20dB nHL exceeded those of the normative group, a slight hearing loss was diagnosed.

Acoustic reflex thresholds at varying click rates in children.

Objective: Previous studies conducted with young adults have shown that ipsilateral acoustic reflex thresholds improve with an increase in the click-rate. Older adults also show an improvement in acoustic reflex thresholds with an increase in the click-rate. However, the click-rate induced facilitation (RIF) of acoustic reflex thresholds is significantly reduced in older adults.

Can maximum comfortable loudness levels in hearing impaired listeners be predicted from ipsilateral acoustic reflex thresholds recorded with high frequency probes?

This study was designed to test the effectiveness of the ipsilateral acoustic reflex thresholds measured with low and high frequency probes in predicting the maximum comfortable loudness levels (MaxCLs) in hearing-impaired subjects using recently available sophisticated procedures for acoustic reflex and loudness measures. Loudness growth functions were measured in hearing-impaired subjects at .5, 1 and 2 kHz using a computerized procedure.

Auditory brainstem responses in Rett syndrome: effects of hyperventilation, seizures, and tympanometric variables.

This study examined the effects of tympanometric variables, stage of disease, hyperventilation, and seizures on the auditory brainstem response (ABR) in Rett syndrome (RS). Thirty-four female children with RS ranging in age from 2 years, 3 months to 15 years, 7 months participated in the study. ABRs and tympanograms were recorded from all of the subjects.

Effect of probe frequency and gender on click-rate-induced facilitation of the acoustic reflex thresholds.

This study evaluated the effects of probe frequency and gender on the click-rate-induced facilitation of the acoustic reflex thresholds (ARTs). ARTs were measured by delivering clicks at the repetition rates of 60, 120, 180, 240 and 300/sec. The probe tones were 226, 678 and 1000 Hz.

Ipsilateral acoustic reflex thresholds were obtained from 19 left ears by presenting 300 clicks at the repetition rates of 50, 100, 150, 200 and 300/s. The results showed an improvement in the acoustic reflex thresholds with an increase in the repetition rates (rate integration).

Effect of aging on the click-rate induced facilitation of acoustic reflex thresholds.

Acoustic reflex thresholds are known to improve with an increase in the click-repetition rates from 50/sec to 300/sec. In the current study this improvement was used to evaluate auditory processing in older subjects. Acoustic reflex thresholds were obtained from 16 human adult ears within each of the following four groups: young male, young female (18-28 years), older male and older female (50-65 years).

Ipsilateral acoustic reflex thresholds at varying click rates in humans.

The effects of the click repetition rates on the ipsilateral acoustic reflex thresholds were investigated in 17 normal female subjects (total 34 ears) within the age-range of 20 to 26 years. The acoustic reflexes were elicited in response to condensation clicks (100 microseconds duration) at repetition rates of 50, 100, 150, 200, 250 and 300/sec. The probe tone frequency was 226 Hz and the intensity was 85dB SPL.

Homo- and anti-phasic stimulation in ABR.

Effects of homo-phasic and anti-phasic stimulation on the binaurally evoked auditory brain-stem responses (ABRs) were investigated in 10 normal subjects. Clicks were presented at 47 dB SL with two in-phase (binaural condensation and binaural rarefaction) and two out-of-phase (left ear condensation, right ear rarefaction and right ear condensation, left ear rarefaction) stimulus configurations. The earlier of the latencies obtained with homo-phasic stimulation were compared with the earlier of the latencies obtained with anti-phasic stimulation.
