SmarterNoise - Noise recorder 1.071

SmarterNoise is a comprehensive sound level meter designed to measure sound levels in both video and audio modes, as well as provide information on noise exposure risks. This tool allows for recording video and sound, along with the ability to run the app in the background for continuous monitoring.

Main features of SmarterNoise include a built-in camera, optional location tagging, and convenient sharing of measurement results. Users can easily access saved video and audio files from the archive within the app, taking sound level and noise measurements to a new level of sophistication.

Distinctive smart icons in SmarterNoise react to measured sound levels in accordance with cutting-edge research focused on understanding the health and well-being implications of noise pollution. These icons offer insights into how noise exposure can impact hearing, cognitive performance, health, and overall well-being at varying levels of noise intensity.

About Decibels and Sound Measurement:

The unit used for measuring sound intensity is called a decibel. Since the decibel scale is logarithmic, a sound with twice the intensity of a reference sound corresponds to an increase of approximately 3 decibels. Understanding that each 10-decibel increase equates to a tenfold intensity increment from the reference point is vital as even small changes in decibel levels can significantly affect noise perception.

The preferred method for expressing varying sound levels through a single decibel value across a period is Leq. Commonly, sound levels are measured using A-weighting to focus on frequencies detectable by the human ear. In this context, Leq becomes LAeq, which emphasizes higher peaks to provide a holistic noise reading. SmarterNoise adopts LAeq for all its measurements.

About Noise:

According to World Health Organization (WHO) reports, noise ranks as the second most significant environmental contributor to health issues after air quality. Despite increasing general environmental awareness, the detrimental effects of noise remain largely underestimated by the public. Urban populations face constant exposure to noise pollution at home and work due to factors such as traffic congestion, air travel expansion, urbanization, and industrial noise emissions. SmarterNoise aims to enhance understanding of noise-related concerns amid our modern-day noisy environments.
