Charlie Mydlarz
Research Assistant Professor
Brooklyn

I am a Research Assistant Professor at New York University’s Center for Urban Science and Progress (CUSP) and the Music and Audio Research Lab (MARL). My current research interests include the design, development, and deployment of advanced urban IoT devices for city scale noise monitoring.

Profile

The main focus of my work is on the development and implementation of cyber-physical systems for large-scale, high-resolution soundscape data capture from urban environments with a lean towards acoustic sensor development using digital MEMS microphone solutions. This is part of the NSF funded Sounds Of New York City (SONYC) project.

My PhD work at The University of Salford’s Acoustic Research Centre enabled public engagement in a large-scale mass participation soundscape study using smart phones for global subjective and objective data collection and analysis. The data collected can be explored at soundaroundyou.com. My past research projects also include the influences of sound environments on the attainment of 11-16-year-old school children in England. I completed my BSc in Audio Technology with first class honors at the University of Salford in 2007.

Projects

SONYC

This is how Ive spent most of my working time in NYC, working on the Sounds Of New York City or SONYC project. I designed, fabricated and deployed a network of over 60 low-cost acoustic sensor nodes across the city to provide continuous, real-time, accurate and source-specific monitoring of urban noise. This enables large-scale analysis of urban noise activity to reveal noise patterns across space and time. These tools have been used to drive a data-driven approach to noise mitigation by feeding relevant, actionable, and timely information to those tasked with reducing noise. A number of the sensor nodes have been operational since May of 2016, resulting in the accumulation of vast amounts of calibrated sound pressure level (SPL) data.

REIP

The Reconfigurable Environmental Intelligence Platform (REIP) aims to alleviate many complex aspects of remote sensing, including sensor node design, software stack implementation, privacy issues, bandwidth, and centralized compute limitations, bringing down start up times from years to weeks. REIP will be a plug-and-play remote sensing infrastructure with advanced edge processing capabilities for in-situ insight generation. At the core of REIP is a set of hardware modules that connect together to form a sensing solution. Each sensing module will come in a number of variants allowing the user to find the proper tradeoff between complexity/cost and power/features. The REIP infrastructure will expand the use of audio-visual sensing architectures beyond the highly specialized research groups that are able to design, build, and purchase all the necessary components and make it available to a wider community as a research infrastructure. REIP will be tested on real-world applications, including observation, integrated sensing transportation networks, and indoor sensing for reducing waste in HVAC (heating, ventilating, and air conditioning) systems. Experts will be able to customize each application domain.

Sound Around You

My PhD project where people across the world were prompted to use their iphone (or any other audio recorder) to capture clips of around 30 seconds in length from different sound environments, or soundscapes. Anything from a family car journey to a busy shopping centre, and to upload them to our online map, along with their opinions of them and why they chose to record it. I did this to investigate how sounds in our everyday environment make us feel.
