Ninabadilishaje dB kuwa Pascals?

p = p_ref × 10^(SPL/20), where p_ref = 20 μPa (= 2×10⁻⁵ Pa), the threshold of hearing.

Shinikizo la kumbukumbu kwa dB SPL ni nini?

Shinikizo la kumbukumbu la sauti ni 20 μPa (micropascals) au 2×10⁻⁵ Pa, inayolingana na kizingiti cha karibu cha usikivu wa binadamu katika 1 kHz.

Uzito wa A hurekebisha viwango vya sauti vilivyopimwa ili kukadiria unyeti wa usikivu wa binadamu. Hupunguza masafa ya chini ( 6 kHz) frequencies. dBA is the A-weighted unit. Because the correction is frequency-dependent, a single dB(A) value cannot be converted to sound pressure in Pa without knowing the frequency spectrum — this converter works with unweighted dB SPL only.

0 dB ina nguvu kiasi gani?

0 dB SPL inalingana na shinikizo la 20 μPa — kizingiti cha karibu cha usikivu wa binadamu. Si ukimya, bali sauti ya chini kabisa ambayo watu wengi wanaweza kusikia.

Kizingiti cha maumivu kwa dB ni nini?

Kizingiti cha maumivu ni takriban 130–140 dB SPL, ikilingana na shinikizo la sauti la takriban 63–200 Pa.

Kibadili cha Kiwango cha Sauti

Convert between unweighted sound pressure level (dB SPL) and sound pressure (Pa). Enter a value in either unit and get an instant conversion. Note: A-weighted levels in dB(A) are not directly convertible to Pa.

SPL = 20·log₁₀(p/p₀)dB SPL ↔ PaUnweighted

where p₀ = 20 μPa = 2 × 10⁻⁵ Pa (threshold of hearing)

A Note on dB(A)

This converter works with unweighted sound pressure levels (dB SPL). An A-weighted level, dB(A), applies a frequency-dependent correction curve that approximates human hearing sensitivity. Because the correction varies with frequency, a single dB(A) value cannot be converted to sound pressure in Pa without knowing the frequency spectrum of the sound. Do not enter dB(A) readings into this tool expecting an exact pressure value.
