We studied the level of music loudness to which operators of music recording/retail centre were exposed in order to determine their risk of work-related hearing loss. A survey of consenting operators of music recording centres on six main streets selected by simple random sampling at different locations of the town was carried out using a structured questionnaire. The sound level of the music from the music player speakers in each centre was measured using a sound level meter (Testo 815) duly calibrated with a sound level meter calibrator (Testo 0554.0009). Results were analyzed by simple descriptive statistics. The study involved 79 mainly male young adults aged 27.7 ± 6.8 years (SD). The measured sound levels in the centres ranged from 86-104dBA; with a mean of 96 ± 2.5dBA(SD). Exposure to this music loudness was for an average of 9 hours daily for an employment period averaging about 5 years. Thirty percent of the study population reduced music loudness by turning down the volume; 6.3% sat at six or more metres from the speakers; 10% used ear plugs occasionally and 7.6% had hearing assessment at some stage prior to the present study. The level of noise exposure of this population of young males is in excess of the threshold associated with irreversible hearing loss, and protection measures were less than optimal.

INTRODUCTION: Recreational noise exposure has become a major threat to the hearing system, and this includes exposure to loud noise during group exercises such as Zumba Fitness, where loud music plays an important role. This study aimed to assess the noise exposure and hearing threshold profile among Zumba Fitness regulars in Kuantan, Malaysia. MATERIALS AND METHODS: Noise exposure and hearing profile threshold were measured during Zumba Fitness sessions at a fitness studio in Kuantan, Malaysia from 24th June 2014 to 12th August 2014. Noise exposure was measured using a noise dosimeter for one hour of Zumba Fitness session with a total of nine sessions run by three different instructors while sound level pressure was taken using a sound level meter during ambient, peak session and during cooling down. Thirty participants answered questionnaires and underwent pure tone diagnostic audiometry test at a local clinic for hearing threshold documentation. RESULTS: Some areas of the hall posed higher risks of causing noise-induced hearing loss especially near the amplifiers. There were periods when the hearing level exceeded 115 dBA. Early abnormal pattern could be observed in the hearing profiles of some of the participants to suggest preliminary hearing problems. CONCLUSION: Zumba Fitness regulars have a risk of developing noise-induced hearing loss and preventive steps should be properly addressed as NIHL is permanent and irreversible.

Abstract: Excessive use of headsets for a long period of time may cause hearing loss. While using a headset, the ears receive sound waves which are converted into electrical pulses transmitted to the auditory cortex via the auditory nerve. Exposures to noises can damage the cochlea hair cells that worsen the degenerative process of the auditory nerve. Radio announcing is one of the professions with a frequent use of a headset. This study aimed to find  the difference of the auditory functions between people who used headsets frequently and those who did not use headsets. This was a case-control study consisting of a group of people frequently using headsets (radio announcers, the case group) and a group without using headsets (non-radio announcers, the control group). Each group consisted of 20 respondents aged 20-40 years. Hearing functions were measured by using an audiometer while the noise levels generated by the headsets were measured with a sound level meter. The results showed that by using the Fisher exact test, there was a highly significant relationship between the usage of headsets and the hearing loss of the respondents’ left ears  (P = 0.001 <0.01) and right ears (P = 0.010 <0.05). Conclusion: There was a difference of hearing in both ears between the radio announcers and non-radio announcers. Keywords: noise exposure, headset, hearing function, radio announcer.     Abstrak: Pemakaian headset berlebih dalam kurun waktu yang lama dapat menimbulkan gangguan pendengaran. Pada penggunaan headset, telinga menerima gelombang suara yang kemudian diubah menjadi pulsa listrik yang diteruskan ke korteks pendengaran melalui saraf pendengaran. Pada telinga yang terpapar bising untuk waktu lama dapat terjadi kerusakan sel-sel rambut di koklea saraf pendengaran yang memperburuk proses degenerasi saraf pendengaran. Penyiar radio merupakan salah satu profesi dengan tingkat pengunaan headset yang cukup tinggi. Penelitian ini bertujuan untuk mendapatkan perbedaan fungsi pendengaran antara pengguna headset dan yang tidak menggunakan headset. Penelitian ini merupakan studi kasus-kontrol (case-control study) dengan melakukan perbandingan antara kelompok yang memakai headset (penyiar radio, kelompok kasus) dan kelompok lainnya yang tidak memakai headset (bukan penyiar radio, kelompok kontrol). Masing-masing kelompok terdiri dari 20 responden berusia 20-40 tahun. Fungsi pendengaran diukur dengan audiometer sedangkan tingkat kebisingan yang ditimbulkan oleh headset di ukur dengan sound level meter. Analisis statistik menggunakan uji Fisher exact menunjukkan terdapat hubungan yang sangat bermakna antara penggunaan headset dan gangguan pendengaran pada telinga kiri (P = 0,001 <0,01) dan telinga kanan (P = 0,010 <0,05). Simpulan: Terdapat perbedaan fungsi pendengaran kedua telinga antara penyiar radio dan yag bukan penyiar radio. Kata kunci: paparan bising, headset, fungsi pendengaran, penyiar radio.

One wildly used method to reduce and control the noise pollution in green city’s buildings is using sonic-absorbent panels. Their applications can be multiple, such as the insulation of buildings, acoustic barriers and fences along the highway or in front of supermarkets, hospitals and other public buildings. This paper presents a method for testing the behavior of sonic-absorbent panels in open-air environment. The work represents a carrying on of previous research about absorbent materials from gypsum family, tested in lab conditions. The experiment setup used a dynamic installation and as a sample a stand formed by six sonic-absorbent panels from special modeling alpha-gypsum plaster. This installation has been composed of two loudspeakers for emitting the sound at a well-defined frequency by the first laptop, the microphone for detecting and transmitting the signal to the second laptop for analyzing and processing the data. All operations were performed using MATLAB Programs, while a Data Logger Sound Level Meter type CENTER 332 was put on near the microphone to compare both results. The first experiment of acoustic stand has been realized by setting up the installation at a frequency from 50 Hz to 1250 Hz and altering the distance between loudspeakers and stand at 0.5m to 1m and 1.5m, respectively. The second experiment kept the same test’s conditions, while two and three layers of sonic-absorbent panels formed the stand, respectively, but at same distance from source of 0.5 m. In both tests, the results underlined the good sonic-absorbent properties of these panels, especially at medium and high frequency, which can recommend using the panels for multiple outside applications.
