dB Calc Pro
Acoustic Math for Engineers
$2.99 · Designed for iPad
Precision Engineering for Acoustic Professionals dB Calc Pro is a specialized utility designed for acoustic engineers, environmental consultants, and sound technicians who require rapid, accurate, and field-ready decibel calculations. Moving beyond basic arithmetic, this app handles the complex logarithmic nature of sound with a suite of industry-standard formulas.
Key Technical Capabilities:
- Logarithmic Summation & Averaging: Effortlessly calculate the total energy sum or arithmetic mean of multiple sound pressure levels.
- Background Noise Correction: Isolate target signal levels by subtracting interference and background noise using professional compensation algorithms.
- Distance-Based Propagation: Predict sound reduction over distance from a point source in a free field, accounting for slant distance and height.
- Enclosing Surface (Box Source) Analysis: Seamlessly convert between sound power level and sound pressure level based on the dimensions of a boxr-shaped surface.
- Wizard-Style Entry: Minimize input errors with a structured, step-by-step entry system for complex multi-parameter calculations.
Optimized for the Field:
- Left-Handed Ergonomics: A dedicated mode that mirrors the interface, placing the numeric keypad on the left for comfortable one-handed operation.
- Technical Precision: Results are formatted according to engineering standards, featuring scientific subscripts and precise units
- Reference Guide: Integrated formula library for on-the-spot verification of acoustic principles.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
- Safety Guardrails: Integrated input validation prevents physically impossible decibel entries (> 200 dB) while allowing for unrestricted distance and dimension inputs.
- Adaptive Layouts: Bug fixed for large iPhone screens and landscape use with an "elastic" keypad and flexible UI components that prevent clipping.
