Sound Level Converter
Convert between different sound level units including decibels, bels, nepers, and various decibel scales
Standard logarithmic unit
1 Bel = 10 decibels
Sound Level Reference:
Common Sound Levels (dB SPL):
- • Threshold of hearing: 0 dB
- • Whisper: 20-30 dB
- • Normal conversation: 60 dB
- • City traffic: 80-90 dB
- • Rock concert: 110-120 dB
- • Pain threshold: 130 dB
Unit Relationships:
- • 1 Bel = 10 dB
- • 1 Neper ≈ 8.69 dB
- • dB(A): A-weighted for human hearing
- • dB SPL: Sound pressure level
- • dB HL: Hearing level (audiometry)
About Sound Level Converter
A comprehensive sound level converter tool that allows you to convert between various acoustic measurement units. Whether you're working in acoustics, audio engineering, noise control, or environmental monitoring, this tool provides accurate conversions between decibels, bels, nepers, and different decibel reference scales used in sound measurement.
Why use a Sound Level Converter?
Sound level conversion is essential in acoustics, audio engineering, and noise control. Different applications use different decibel scales and reference values - dB SPL for sound pressure, dB(A) for A-weighted measurements, dB HL for hearing levels, and specialized units like bels and nepers for logarithmic calculations. This tool ensures accurate conversions between these units for proper acoustic analysis.
Who is it for?
This tool is perfect for acoustic engineers, audio engineers, noise control specialists, environmental consultants, audiologists, sound technicians, students studying acoustics, and professionals working with sound measurements who need accurate sound level unit conversions.
