Wasoma rorogo
Na wasoma rorogo (Vosa Vakavalagi: Audio frequency, AF) e dua na veigauna yavavala ni ka kena rorogo e rogoci ki na tamata vakatautauvata. Na SI iuniti ni vakawasoma na hertz (Hz). Sa ikoya na iyau ni rorogo e vakatau vakalevu duadua na kena iqaqi.[1]
Na ivakatagedegede ni rogorogo e ciqomi raraba me baleta na tamata e 20 ki 20,000 Hz.[2][3][4] Ena cagi ena veivakasaurarataki ni cagi, oqo e vakatayaloyalotaka na ua rorogo kei balavu ni rorogo ni 17 metres (56 ft) ki 1.7 centimetres (0.67 in). Na vakawasoma e ra ni 20 Hz e dau vakilai vakalevu ka sega ni rogoci, vakasamataka na veisautaki ni veivakayavalati e levu sara. Na rorogo ni rorogo e cake mai na 20 kHz e vakatokai me ultrasonic.
Na rorogo e tete me vaka na galu ni vakamisini yavavala ua ni veivakasaurarataki kei na veisau, ena cagi se so tale na ka.[5] Ena kena levu, na veitiki ni vakawasoma ni dua na rorogo e vakadeitaka na kena "roka", na kena timbre. Ni da vosa me baleta na kena wasoma (ena duabau) e dua na rorogo, e kena ibalebale na iyau e vakatau vakalevu duadua na kena iqaqi.[6] Na iqaqi cecere e tiko kina na rorogo cecere, kei na iqaqi lailai e lailai na kena rorogo.
Na wasoma e rawa ni rogoca e dua na daliga e vakaiyalayala ga ena dua na ivakarau ni wasoma. Na wasoma rorogo iwiliwili me baleta na tamata e dau soli me vaka ni tiko ena maliwa ni rauta ni 20 Hz kei 20,000 Hz (20 kHz), e dina ga ni iyalayala ni wasoma cecere e dau vakalailaitaka na yabaki. Na so tale organism e duidui na kena rogorogo. Kena ivakaraitaki, eso na mataqali koli era rawa ni raica na veivakayavalati me yacova na 60,000 Hz.[7]
