Noise Analysis & Monitoring
Noise type identifier, noise pollution meter with WHO guidelines, sleep environment noise checker, OSHA noise exposure calculator, appliance hum detector, HVAC noise analyzer, low-frequency noise detector, noise color analyzer, and noise level logger — for health-conscious users, remote workers, safety officers, homeowners, and researchers.
Available Tools
Noise Type Identifier
Record ambient noise and identify its type — hum, hiss, buzz, rattle, rumble, white noise, or tonal. Frequency analysis identifies the likely source (electrical, mechanical, airflow, structural) and suggests remediation steps to reduce the noise.
Launch tool →Environmental Noise Monitor
Continuously monitor ambient noise levels with real-time dB display and time-series chart. Track min, max, Leq (equivalent continuous level), and L90 (background level) statistics, set alert thresholds, and run extended monitoring sessions.
Launch tool →Noise Pollution Meter
Measure your environment’s noise level against WHO and EPA health guidelines. Traffic light health risk indicators (green/yellow/red), recommended maximum exposure durations at current level, and exportable noise complaint documentation report.
Launch tool →Appliance Hum Detector
Detect and identify 50/60 Hz electrical hum and its harmonics (120, 180, 240 Hz) from household appliances. Identifies likely source type — transformer, fluorescent lighting, motor, or ground loop — with targeted remediation suggestions.
Launch tool →Noise Spectrum Analyzer
Real-time FFT frequency spectrum analysis of ambient noise. Identify dominant frequencies and correlate them to noise sources, apply A/C/Z frequency weighting, peak hold display, and export spectrum screenshots for documentation or troubleshooting.
Launch tool →Noise Floor Analyzer
Measure the noise floor of your environment or audio equipment chain in dBFS and dBA. Noise floor spectrum display, quality rating (broadcast studio/professional/consumer grade), and comparison against recording and broadcast standards.
Launch tool →Office Noise Level Checker
Check if your workspace noise meets productivity and health standards. Real-time dB measurement with productivity impact chart (<50 dB optimal, 50–70 moderate, >70 detrimental), OSHA workplace comparison, and open office vs closed office reference benchmarks.
Launch tool →Sleep Environment Noise Checker
Analyze your bedroom noise for optimal sleep conditions. Measures dB level against sleep research standards (<30 dB ideal, 30–40 acceptable, >40 disrupting), identifies noise sources by frequency (traffic rumble vs neighbor sounds), and suggests masking noise options.
Launch tool →Noise Color Analyzer
Record noise and classify it by spectral color — white (flat), pink (−3 dB/octave), brown (−6 dB/octave), blue (+3 dB/octave), violet (+6 dB/octave), or grey. Visual spectrum slope comparison, dB/octave measurement, and explanation of each noise color’s characteristics and uses.
Launch tool →Noise Exposure Calculator
Calculate your daily cumulative noise exposure (dose) based on dB levels and durations throughout the day. Time-weighted average (TWA), OSHA (90 dB/8 hr) and NIOSH (85 dB/8 hr) compliance check, dose percentage, and hearing protection recommendations.
Launch tool →Noise Level Logger
Log noise levels continuously over extended periods with timestamps. Real-time dB chart over time, Leq/L90/Lmax statistical summary, configurable measurement intervals, CSV data export for reporting, and session-to-session comparison for before/after analysis.
Launch tool →Low Frequency Noise Detector
Detect problematic low-frequency noise and hum below 100 Hz that may be difficult to perceive directly. Sub-bass spectrum analysis, 50/60 Hz mains hum + harmonics detection, infrasound (<20 Hz) identification, “the Hum” reference frequencies, and vibration vs airborne noise guidance.
Launch tool →HVAC Noise Analyzer
Analyze HVAC system noise to diagnose problems. Frequency analysis targeting common HVAC noise bands, fan blade passage frequency calculation, duct resonance identification, NC (noise criteria) curve comparison, and problem-specific diagnostic suggestions.
Launch tool →Traffic Noise Analyzer
Measure and characterize traffic noise with continuous monitoring. Frequency breakdown separating engine rumble from tire whine, time-of-day pattern analysis, comparison with residential noise standards, and peak vehicle event detection and logging.
Launch tool →Noise Comparison Tool
Compare noise measurements from different locations, times, or before/after treatment. Side-by-side spectrum overlay, dB difference display, statistical comparison (Leq, Lmax, L90), and exportable before-and-after report for documentation.
