Citlivosť reprosústav SPL (dB/W/m)

GlossarySpeakersCitlivosť reprosústav SPL (dB/W/m)

Parameter citlivosti vám hovorí, akú hlasitosť (akustického tlaku) v dB dosiahnu reprosústavy vo vzdialenosti jedného metra pri excitácii výkonom 1 W.

Ak ide o pasívne reprosústavy, mnoho kupujúcich sa orientuje podľa maximálneho udávaného príkonu. Ten vám však iba hovorí, aký trvalý príkon RMS reprosústava znesie dlhodobo bez poškodenia.

Na to, aby ste zistili, ako hlasno bude reprosústava pri určitom príkone (W) hrať, je však dôležité poznať hodnotu citlivosti. Ak má reprosústava napríklad citlivosť 90 dB/W/m, znamená to, že pri príkone 1 W bude vo vzdialenosti 1 m hrať hlasitosťou 90 dB. Na každé 3 dB hlasitosti bude potrebovať dvojnásobný príkon. Ak sa vám zdá, že nepočúvate pri hlasitosti 90 dB a vystačili by ste si teda teoreticky aj so zosilňovačom s výkonom 1 W RMS na kanál, mýlite sa. Určitá výkonová rezerva je dôležitá na vykrytie dynamického rozsahu hudby.
