Mitezo: Kuparara uye Zvimwe
Iyi girafu inoratidza kukanganiswa kwehurmonic yese ye QC25 yakaenzana pa 90 uye 100 dBA. Aya ndiwo manzwiro ekuteerera zvakanyanya-iwe haungateereri pazwi iroro. Iko kunokanganisa kunopera zvishoma, kunyangwe kunyanya kumafambiro akaderera. Iko 90 dBA inovhara yakanyatsonaka uye inenge isisina kusiyanisa pakati nepakati uye inofamba uye inenge 4 muzana THD pa20 Hz. Pamusoro pe 100 dBA, kune spike yakatsauka pakati pe2 ne3 kHz, uye zvishoma zvepass distortion (3 muzana pa 60 Hz uye pasi, zvichikwira kusvika 6 kubva muzana pa20 Hz). Ungagona here kunzwa izvi? Zvichida kwete. Chikumbaridzo chekunzwika kunonzwika mukutengesa subwoofer kakawanda kunofungidzirwa kunge kunenge 10 muzana.
Mhinduro yakaparadzaniswa yakashandurwa zvishoma ne-high-impedance (75 ohms) mutsara weshoko rekuedza, iyo inofanidza zvaunonzwa apo unoshandisa sefoni yakashata yakakura seye yakavakwa mumapuraneti akawanda. Nheyo dzacho dzakaderera ne -4 dB pa20 Hz, uye inofamba inenge -1 dB pamusoro pe4 kHz. Zviri pachena, Bose ari kuita chimwe chinhu zvishoma zvakasiyana pano.
Nekunzwisisika pa 32 ohms, iyo yakaenzana ne 1 mW signal pakati pe 300 Hz ne 3 kHz pa 32 ohms impedance, ndeye 97.2 dB mu passive (NC-off) mamiriro uye 101.3 dB inoshanda (NC-on) mamiriro. Izvi zvakakwana kupa huwandu hwehuwandu kubva kune imwe nzvimbo neCN pamusoro, uye zvakakwana kubva kune vose kunze kwezvinhu zvisina simba zvakanyanya neCN off.
