Cuspart vs Sound Level Meter

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.

Measure noise like a pro — straight from your iPhone. Sound Level Meter: Decibel turns your iPhone into a precision SPL meter, engineered to the IEC 61672-1 international standard. Protect your hearing, document a noise complaint, tune a studio, or pre-check a workplace - reliable readings in seconds, clean A4 PDF reports in one tap. KEY FEATURES • Real-time dB readings with A, C and Z weighting — switch on the fly • Fast (125 ms), Slow (1 s) and Impulse time integration — the modes pros use • 1/3-octave frequency analysis • Multiple live visualizations: histogram, gauge, circle meter, applause meter, basic graph • All metrics in one place: LAeq, Min, Max, Avg, Peak • Save full measurement sessions with timeline, location and notes • Calibration screen for fine-tuning against any reference meter • Available in English, French, German, Spanish, Italian, Japanese, Chinese • Distraction-free dark interface focused entirely on your data DESIGNED FOR ACCURACY Sound Level Meter: Decibel follows the IEC 61672-1 sound level meter specification: • True biquad-cascade A and C weighting filters — not generic high/low-pass approximations • Exponential averaging on squared pressure (the correct method) • Per-device calibration based on the iPhone hardware actually in use • User-adjustable offset to align with any reference meter or calibrator IDEAL FOR • Audio engineers tuning studios, venues and rehearsal spaces • Workplace safety pre-checks before a formal acoustic survey • Musicians, DJs and podcasters watching their hearing exposure • Parents monitoring nursery or kids' bedroom noise levels • Tenants documenting noise from neighbors, traffic or construction • Anyone serious about long-term hearing health FAQ How accurate is it? After one-time calibration against a known reference, expect 2–3 dB of typical accuracy in the 40–95 dB range. Maximum measurable level is bounded by your iPhone hardware (around 104–110 dB). Does it replace a certified sound level meter? For monitoring, awareness and personal documentation: yes. For legally certified acoustic measurements, dedicated class 1/2 hardware remains the reference. Can I export my measurements? Every saved session generates an A4 PDF with full stats and the timeline graph. Print it, email it, AirDrop it — anywhere PDFs work. Why do I see different values than another decibel app? iPhone microphone sensitivity varies between models, and each app handles calibration differently. Use the built-in calibration screen to align with a trusted reference. How is my data handled? Sessions are stored locally on your iPhone. Nothing is uploaded — your acoustic data stays yours.
