mini dB-Rechner 1.3

mini dB-Rechner is a compact decibel calculator designed for quick, reliable audio, acoustics, and electronics calculations. It helps you convert between dB and linear values, work with power and voltage/amplitude ratios, and use common reference scales such as dBu, dBV, and dB SPL. You can combine or compare levels, estimate attenuation over distance in typical free-field scenarios, and determine the gain or attenuation needed to reach a target level. A clean, minimal interface keeps the focus on accurate numbers and clear units, making it a handy tool for everyday engineering tasks and educational use.

Highlights:

• Convert dB ↔ linear ratios for power and amplitude
• Work with common references (dBu, dBV, dB SPL)
• Sum or compare levels and assess signal differences
• Estimate distance-related level changes (e.g., 6 dB per doubling)
• Enter and view values with clear, consistent units

Note: Calculations assume ideal conditions. For critical work, verify results with calibrated measurements and appropriate safety margins.
