Kui keskmised noise measurements töökohal exceeds It's value, peaksite ostma SNR-parameetriga headphones, which reduces mürataset 85 dB-ni or alla It's. eeldades, et töötame entire time kõrvaklappe kandes parameetriga snr 32 and töökeskkonnas, which noise intensiivsus on 116 dB, siis vähendame noise 84 dB-ni.
Kui operaatori kõrvaklappide kandmise time is longer than several minutes, tasub more attention to rotate disainielementidele, which parandavad their kandmise mugavust. enough wide nahasõbralikest materials tihenduspadjad peaksid mahtuma entire user kõrvarõngale. peapaela soft upholstery Decreases pressure head ülaosale. aga strength, millega headphones head mounting kinnituvad, are not affected not only mugavust, only also summutuse efficacy, therefore tasub continuous for use valida not tingimata highest saadaoleva, only sobivalt chosen snr parameetriga headphones.
