SoundMeter X vs Cuspart

SoundMeter X turns your iPhone or iPad into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, stereo signal generator, multi-channel data recorder, and real-time whole or 1/3 octave band spectrum analyzer (subscription or perpetual license required for most features--14-day free trial available). Input signals can be acquired from any available audio input path. Sensitivity calibration can also be performed for any audio input device and/or input channel. Direct hardware support (automatic sensitivity calibration, based on factory-defined values) for The Modal Shop’s 2-channel 485B39 USB-ICP interface and miniDSP’s UMIK-1, UMIK-2, and EARS microphones. In addition to real-time sound level measurements, SoundMeter can stream raw sound data to audio files, and store acquired sound level data, including date, time, and location, in CSV or TXT (tab-delimited) files, MAT-files, or high-resolution PDF images for later retrieval from your device. SoundMeter may be downloaded for free from the App Store. Additional tools and features are offered via in-app purchase. The SoundMeter Pro subscription includes: - User-defined custom metadata in saved audio and data files - Level MeterLp, Leq, Lx sound levels -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. -- Event notifications - Max Levels Meter -- Traffic-light-style meters make it easy to monitor 2 separate sound level thresholds in 2 independent user-defined frequency bands. -- Define lower (warning) and higher (limit) sound level thresholds for overall (full audio band) levels as well as for individual octave frequency bands. -- Store user-defined thresholds in files for later recall. - Noise Dosimeter -- 8-hour Noise Dose, Projected Dose, TWA calculations -- Criterion Levels: 80, 85, 90 dB -- Exchange Rates: 3, 4, 5 dB -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. - Real-time Octave Spectrum Analyzer (RTA) -- Lp, Leq, Lx sound levels -- Supports whole or 1/3-octave frequency bands -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- NC, RNC, and NR references curves, NC, SIL, and NR values -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. - Multi-channel Data Recorder -- Supports up to 8 channels -- Live monitoring of recorded data -- Metadata (including calibrated sensitivity) embedded in audio file (AIF, CAF, WAV), optionally saved in separate data file - Stereo Signal Generator -- Left and right outputs assigned to arbitrary hardware output channels -- Random and pseudorandom (periodic) noise sequences with white or pink spectrum -- Linear and logarithmic frequency sweeps -- Dual periodic waveforms with arbitrary frequency and phase difference - MultiTool -- Powerful data monitoring and project management (Add 2-6 subtools, depending on screen size, and save configurations for easy recall at a later time.) The SignalScope X Pro Tool Set subscription can be shared between SoundMeter X and SignalScope X. It unlocks all tools and features of the SoundMeter Pro subscription in SoundMeter X and all tools and features of the Pro Tool Set subscription in SignalScope X (iCloud login required).

Professional Decibel Meter: Analysis, Recording & Alerts Overview Developed for environmental acoustic measurements and noise auditing, this application transforms your mobile device into a professional sound analysis station. With advanced signal processing algorithms, real-time data visualization, automated threshold alerts, and location-based video documentation, it offers precise solutions for occupational safety, environmental inspection, and acoustic analysis needs. KEY TECHNICAL FEATURES Smart Threshold Alarm & Notification System: No need for constant screen monitoring. When noise levels exceed user-defined limits or standard safety thresholds (e.g., 90 dB), the application automatically sends instant notifications. This proactive warning mechanism allows you to immediately detect high noise exposure and helps protect hearing health. Video Documentation & Geo-Tagging: Verifiability of measurement data is essential. During video recording, the application overlays instant decibel (dB) values, GPS coordinates, date, and time directly onto the footage. This feature creates irrefutable visual evidence for noise violations, site inspections, and legal dispute resolutions. Dynamic Graphical Analysis: Sound fluctuations are monitored with millisecond precision via time-axis charts. Instant noise changes, peak points, and background noise levels are detailed within the graphical interface. Statistical Data Processing: Data obtained during the measurement session is analyzed to calculate: • Min: The lowest sound level detected. • Max: The highest noise peak level. • Avg: Time-weighted average value calculated automatically. Customizable Interface (UI): To ensure optimal readability under various lighting conditions, the application offers multiple color themes and options for both analog and digital gauge displays. CORPORATE & INDIVIDUAL USE CASES • Occupational Health and Safety (OHS): Automatic detection of noise limit violations in factories, workshops, and industrial sites. • Environmental Auditing: Monitoring noise pollution caused by traffic, construction, or commercial businesses for compliance. • Baby & Sleep Safety: Remote awareness when sound levels rise in a nursery or sleeping environment. • Acoustic Testing: Performance evaluation of sound insulation and audio equipment. Why Choose This Solution? • Proactive Safety: Warning system triggers upon limit breach. • Evidence Quality: Location and timestamped video records. • Data Reliability: Consistent results with calibrated algorithms. Digitize your noise measurement processes.
