Sound Level Analyzer Lite 7.0

Sound Level Analyzer Lite is a sound level meter app available for iPhone. The application finds utility in various scenarios such as measuring environmental noise levels, checking audio systems, assessing vehicle interior noise, monitoring sound levels at live events, and more.

Users can easily configure the frequency weighting and time weighting characteristics required for sound level measurements, enabling precise and accurate results. Additionally, the app includes a calibration feature to adjust microphone levels for each device.

Key Features:

• Sound level measurement metrics (dB): Leq (equivalent noise level), Min (minimum value), Max (maximum value), Avg (time average equivalent noise level)
• Frequency weighting correction characteristics: A (for noise level meter), C (for sound level measurement), Z (no correction)
• Time weighting characteristics: Fast = 0.125 sec, Slow = 1.0 sec
• Calibration function: allows for level correction value setting from -20 to +20dB
• Measurement duration: up to 20 seconds

Applications:

• Live Sound
• Environmental noise measurement
• Audio equipment installation
• Audio equipment tuning
• Architectural acoustics
• Broadcasting
• Device management

Noise Level Examples:

• 130dB: Engine sound of airplane
• 110dB: Car horn
• 100dB: Noise of passing train
• 90dB: In a loud factory
• 80dB: Inside a train, Vacuum cleaner noise
• 70dB: Noisy office, Noisy street sounds
• 60dB: Quiet car noise, Normal conversation volume
• 50dB: Quiet office ambiance
• 40dB: Library noise level, Quiet residential area sounds
• 30dB: Outskirts at midnight, Whispering sound level
• 20dB: Rustling of leaves sound intensity

Note:

Upon first access to the microphone after installing the app, authorization is required from the iOS system. Ensure that microphone access is enabled in the iOS settings under "Settings > Privacy > Microphone" to allow the app to function correctly.

The standard noise measurement range is 30-130 dBA, with even quiet rooms measuring around 30 dBA. Extremely low noise levels such as 0 dBA may not register even in total silence.

The World Health Organization has established connections between noise exposure and health risks including tinnitus, sleep disturbances, stress, cognitive impairments, heart diseases, and general annoyance. Monitoring environmental noise levels can contribute to overall wellness.
