headphones noise against 24dB

Müravastased headphones 74580 ühendavad endas head helisummutusparameetrid disainiga, which has bigger töömugavus without metallelementideta.

• Summutamise effectiveness: SNR 24 dB
• liigutatavate liigeste suitability adjusting
• soft wide tihenduspadjad, which suitable for well head and is manufactured nahasõbralikest materials
• peapaela soft polsterdus

Padja dimesions:

• size A: approximately 40 mm
• size B: approximately 65 mm

Kuidas valida oma töökohale kõrvaklappe:

protective müravastased headphones protect kasutajat harmful noise eest, reducing detsibellides mõõdetavat helitaset SNR parameetri value. 8-tunnise tööpäeva ülempiiriks määrati 85 dB . Kui keskmised noise measurements töökohal exceeds It's value, peaksite ostma SNR-parameetriga headphones, which reduces mürataset 85 dB-ni or alla It's. Eeldusel, et töötame entire time kõrvaklappidega, which SNR on 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 ear. Peapaela soft upholstery relieves pressure head ülaosale. but 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.
