—Noise pollution is one of the most common yet least
regulated environmental hazards facing modern cities. According
to the World Health Organization (WHO), sustained exposure
to sound pressure levels (SPL) exceeding 70 decibels increases
the risk of cardiovascular disease, hearing loss, and cognitive
impairment. Traditional noise monitoring relies on costly, stationary sound level meters (SLMs), which are not suitable for
large and dynamic urban regions [3]. We present NoiseLogger,
a crowdsourced mobile noise monitoring tool for Android devices that transforms typical smartphones into calibrated noise
measurement instruments.
The proposed system architecture consists of three tightly
integrated subsystems: (1) a power-friendly Android foreground
service that continuously collects SPL measurements at 44,100
Hz with a fixed cadence of 12 seconds; (2) a cloud backend
based on PHP/MySQL that stores the collected data, analyzes
persistent noise hotspots using spatial SQL aggregation, and
serves results via a REST API; and (3) an interactive geospatial
map rendered in a WebView using Leaflet.js and Turf.js to
visualize spatiotemporal noise levels on a 30-meter hexagonal
grid with per-cell equivalent continuous sound levels Leq, Lmax,
L10, L90, and hourly Chart.js bar charts. A geofencing module
sends real-time notifications to users when they enter serverdefined high-noise zones.
An early rollout demonstrates that NoiseLogger is capable of
capturing contextualised, geotagged temporal datasets without
requiring dedicated hardware, while effectively targeting areas
of consistent urban noise.
