“…Attenuation depends on various factors, including the distance between the noise source and the receiver [14]. Additionally, it is affected by factors such as the presence of hard surfaces around the sound source, which act as barriers to the propagation of noise to further areas [15].…”

The mining industry employs machines and equipment that generate noise. Noise is an unwanted sound that can cause discomfort to listeners, leading to health issues. One of the health problems caused by noise is Noise-Induced Hearing Loss (NIHL), a hearing impairment resulting from continuous exposure to hazardous noise levels. The Permissible Noise Exposure (PNE) value in the mining industry is set at 85 dB(A). This study aims to assess the risk of noise exposure in relation to the occurrence of NIHL among mineral ore processing workers in the mining industry in Indonesia. The study employs the epidemiological frequency measurement method Relative Risk Ratio (RR). The study categorizes workers into two groups: native mining industry workers and contractor workers in the mining industry. The RR results for each group are 2.68 and 2.76 (RR>1), respectively. These results indicate that the noise-exposed group is at a 2.68-2.76 times higher risk of experiencing NIHL compared to the non-exposed group. Noise exposure in the mining industry poses a high risk of NIHL to workers, necessitating control measures. Control measures involve reducing noise exposure using Personal Protective Equipment (PPE) such as earplugs for workers in noisy areas. The use of earplugs can reduce noise by around 24-32 dB(A). Additionally, some industrial companies conduct awareness programs to encourage workers to use earplugs or other PPE, known as the hearing conservation program.

“…Istilah-istilah yang disingkat akan dijelaskan pada saat pertama kali digunakan. (Bozkurt, 2021) Berdasarkan hasil perhitungan yang disebutkan sebelumnya, dihasilkan data distribusi frekuensi. Kemudian, dengan menggunakan nilai rata-rata, frekuensi interval kebisingan, dan interval itu sendiri, dapatkan distribusi frekuensinya.…”

Pertumbuhan industri tidak dapat dipisahkan dari kebisingan karena hampir setiap aktivitas manufaktur di kawasan industri menghasilkan suara yang terdengar atau terlihat pada tingkat tertentu. Khususnya akibat pengoperasian mesin industri, kebisingan dapat menyebabkan gangguan pendengaran, yang pada gilirannya dapat berdampak pada kesehatan dan kenyamanan. Sebagai bagian dari upaya mengurangi kebisingan latar belakang, PT Petrokimia Gresik telah mulai menerapkan prinsip-prinsip inti Program Konservasi Pendengaran (HCP). Meskipun sebagian program PKP telah dilaksanakan, namun keseluruhan program belum dilaksanakan secara metodis. Tujuan dari penelitian ini adalah menggunakan teknik pemetaan kebisingan dan niosh untuk memastikan lokasi dan volume kebisingan di unit urea PT Petrokimia Gresik di pabrik 1A. Studi lapangan menunjukkan bahwa dua dari tiga wilayah tersebut memiliki tingkat kebisingan lebih tinggi dari tingkat pra-kontrol sebesar 85 dB yang ditetapkan oleh Permenaker NAB No. Per.13/Men/X/2011. Tingkat paparan sebesar 96,53 dB adalah ditemukan di wilayah paling bising. Menurut NIOSH, periode paparan maksimum yang diperbolehkan dapat disesuaikan tergantung pada tingkat kebisingan yang diukur. Periode paparan maksimum yang tercatat di sekitar Stasiun Pompa adalah 33,44 menit, atau 0,56 jam, menurut temuan pengukuran. Karena kedekatan lokasi pengukuran dengan sumber kebisingan, maka karyawan PT Petrokimia Gresik wajib menggunakan helm pengaman, penutup telinga, dan sarung tangan. Pendengaran pekerja dapat dilindungi dari efek berbahaya energi akustik dengan bantuan alat pelindung.

“…This study was conducted in an agglomerate manufacturing industry where workers were exposed to high levels of impact noises in the sanding and classification area. To obtain accurate data on the noise levels, measurements were taken at 6 different points surrounding the M350 ventilator for a duration of 5 days [43] at 4 different hours each day, as depicted in Figure 2. The measurement of noise in decibels, including its frequencies, was carried out with a calibrated sound digital level meter HY1361 to obtain real and exact values of the dB (A) in the measurements.…”

The prevalence of hearing loss among workers in Ecuador is concerning, with up to 40% affected. One of the root causes is the lack of insulation in sources of noise generation. This study presents a practical solution to reduce noise contamination in indoor industrial facilities and to extend the usability of functional old equipment by enabling the addition of accessories, specifically in the sanding and classification areas of an agglomerate manufacturing industry. An isolation camera was designed and implemented using a combination of insulating materials to reduce the noise of a main ventilator and to ensure compliance with local noise regulations. The design and simulation were carried out using CAD tools and the finite element method (FEM) to ensure a simple assembly design, and the camera was manufactured using rapid prototyping tools with lightweight and cost-effective materials, such as wood, foam, and metal. The camera was tested in situ, and its effectiveness was evaluated through functional tests and noise level measurements. The implementation of the camera resulted in a 16% reduction in pressure noise and a 95% reduction in noise frequency. With the additional use of earmuffs, the pressure reduction improved to 44%. These values ensured that noise levels remained 27% below the limit set by Decree 2393, significantly reducing the impact of noise on workers.
