## Description

Your pocket acoustic lab.

Turn your iPhone into a high-precision sound level meter for environmental noise checks, workplace safety, and evidence recording. Get reliable readings plus real-time spectrum analysis and hearing-protection insights.

[Key Features]
• Multiple weighting modes: calibrated dB readings with A/B/C/Z and ITU-R 468.
• Real-time spectrum: high-speed FFT with a clear 20Hz–20kHz distribution.
• Noise exposure tracking: OSHA/NIOSH Dose and TWA with risk alerts.
• Recording for evidence: record while measuring, supports background recording.
• Auto Pause: automatically pauses recording below a threshold and resumes above it.
• iCloud sync: measurements and recordings sync across devices.
• Professional reports: export PDF with trends, max/min/avg, and location.
• Calibration & privacy: manual device calibration; data stored locally or in your iCloud.

[Common Scenarios]
• Neighbor noise evidence: accurately record renovation/party noise levels and recordings to support complaints and dispute resolution.
• Sleep environment monitoring: check bedroom background noise, identify sources that affect sleep, improve rest quality.
• Workplace assessment: monitor noise exposure in factories, construction sites, or offices to prevent occupational hearing loss.
• Appliance noise testing: check whether air conditioners, refrigerators, or ventilation systems exceed limits for quality checks or returns.
• Hearing protection: monitor levels at concerts, clubs, and other loud environments to avoid irreversible hearing damage.
