Publisher Description
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.
Version History - 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. 3.1 Jan 5 - Advanced Calculation Wizards: Specialized modules for Sound Level Summation/Averaging, Interference Compensation, Distance-based Propagation, and Box-Shaped Source (Enclosing Surface) analysis.
- Slot-Based Data Logic: A robust entry system that remembers specific parameter slots. Deleting a measurement now intelligently prompts for that specific missing value.
- Smart Keypad Behavior: Enhanced "C" and "CA" logic—clear your current typing buffer with one tap, or reset the entire calculation with two.
- Ergonomic Layouts: Built-in Left-Handed Mode flips the interface for optimal one-handed operation in the field. 3.0 Jan 2 Support for iPhones with FaceID 2.0 08/29/2019 Uses taptic engine on devices where it is available 1.5 10/11/2016 fixed crash on iOS 8.3 1.4 04/24/2015 improved accuracy for calculation of sound propagation when distance to sound source is more than 100 meters. 1.3 10/30/2014 - Calculation of sound propagation now possible for distances below 100m 1.2 10/20/2014 universal app with iPad support 1.1 10/06/2014 1.0 09/20/2014
