Abstract
Bunyi bising dikaitkan dengan kemerosotan kualiti hidup dengan mengganggu percakapan, mempercepatkan dan meningkatkan perkembangan sikap sosial negatif seperti meragam dan neurosis, dan juga gangguan penumpuan dan seterusnya prestasi dan produktiviti. Dalam kelas, persepsi bunyi dikaburi oleh ambien bunyi bising dan gema(reveberation). Gema berlebihan dan ambien bunyi bising mempunyai kesan negatif yang jelas terhadap persepsi percakapan melalui bunyi yang dicemar (smearing) atau penopengan (masking). Walaupun kehilangan pendengaran adalah perkara biasa dan ketidakupayaan yang biasa berlaku yang mengganggu prestasi pembelajaran kanak-kanak yang bersekolah dalam negara membangun, kanak-kanak dalam era persekolahan jarang disaring pendengaran mereka sewaktu pemeriksaan klinikal rutin, dan pihak berkuasa bidang kesihatan tidak menumpukan sepenuh perhatian terhadap penilaian audiometrik terutamanya di sekolah rendah.
Noise is connected to a deteriorating quality of life, by interfering with speech, by accelerating and escalating the development of negative social behaviors such as irritability and neurosis, as well as interferes with attention and consequently performance and productivity. In classrooms the sound perception is obscured by ambient noise and reverberation. Excessive reverberation and ambient noise have a marked negative effect on speech perception by smearing or masking sound. While hearing loss is a common and considerable disability that harms educational performance of school children in developing countries unfortunately, school-aged children are rarely screened for hearing loss during routine clinical examination, and health authorities pay little attention to audiometric evaluation particularly in primary schools.
