Noise Monitoring in
New Jersey
Class 1 sound data for New Jersey's state and local noise rules.
New Jersey is one of the few states with a comprehensive statewide noise code, and it’s home to some of the nation’s biggest infrastructure projects — the Gateway rail program, the Turnpike rebuild, and constant port and warehouse work. Between the state code and the municipal ordinances layered on top, and with measurements required from certified officers, getting noise right in New Jersey takes professional-grade data.
Specto equips New Jersey contractors and consultants with Class 1 monitoring stations that record around the clock, capture octave-band data, send alerts when a threshold is exceeded, and report automatically. Instead of assembling a system on site, your team installs a configured station and starts documenting conditions from day one — answering questions with data instead of recollection.
Regulatory
The Rules That Apply to New Jersey Projects
New Jersey is one of the few states with a comprehensive statewide noise code. Under the Noise Control Act, NJDEP sets the rules, and municipalities add their own approved ordinances for construction:
- N.J.A.C. 7:29 (state noise code) — sets maximum sound levels for commercial and industrial sources measured at a residential property line: 65 dB(A) during the day (7:00 a.m.–10:00 p.m.) and 50 dB(A) at night, plus octave-band limits
- Municipal construction ordinances — construction and demolition noise is regulated locally through the NJDEP Model Noise Control Ordinance, which municipalities adopt and NJDEP approves, setting construction hours and levels town by town
- Certified enforcement — New Jersey requires noise measurements to be taken by NJDEP-certified Noise Control Officers, trained and recertified through a state-approved course, using instruments that meet the referenced ANSI standards
- Octave-band and measurement methods — the code specifies A-weighted and octave-band criteria and defined measurement procedures (N.J.A.C. 7:29-2), so a Class 1 instrument with octave-band analysis is the right tool
- Federal rules — federal OSHA worker noise exposure requirements (29 CFR 1926.52) and FHWA 23 CFR 772 apply, alongside NJDOT requirements and project-specific permit conditions
Why New Jersey Teams Choose Specto
01
Ready to Deploy: US Inventory
Specto stocks Class 1 noise monitoring systems in the US for rent or purchase. Teams in Newark, Jersey City, Trenton, Camden, and along the Turnpike and port corridors can have monitoring on site in days — before a concern turns into a delay.
02
Field-Ready: Configured Before Shipment
Each station arrives with alert thresholds, reporting schedules, and SvanNET remote access already set. Your crew installs and starts recording, instead of assembling a system on site.
03
State Code and Local Ordinances
New Jersey layers municipal construction ordinances on top of the state noise code, and the governing limits and hours differ from town to town. Specto configures each station to the standard governing your site — including octave-band criteria where they apply — with automated reports built for agency and community review.

The New Jersey Construction Landscape
New Jersey is home to some of the largest infrastructure projects in the country. The Gateway Program — the $16 billion Hudson Tunnel and the new Portal North Bridge — is under construction across the Meadowlands and the Hudson, and the New Jersey Turnpike Authority is beginning a multibillion-dollar rebuild of the Newark Bay–Hudson County Extension, replacing the aging Newark Bay Bridge with new twin cable-stayed spans. Around the ports, warehouse and logistics construction continues at a heavy pace.
Much of this work runs through some of the densest, most closely watched neighborhoods in the country, where community and regulatory scrutiny of noise is high. Continuous monitoring gives New Jersey teams the data they need to document conditions, respond to concerns quickly, and keep work moving.

Our Methodology — How We Work With You
01
Discovery
We start by understanding the project, not by selling equipment. That means scope, timeline, and location; monitoring requirements and regulations; site constraints like power, connectivity, and access; and who needs the reports.
02
System Design and Preparation
We bring together the hardware, sensors, power and connectivity strategy, software setup, alerts, reporting, mounting, and accessories — then configure and prepare the system so it arrives ready for the field.
03
Delivery, Onboarding and Support
We support your team through deployment guidance, practical training, troubleshooting, reporting and alert support, and calibration and service coordination for the life of the project.
New Jersey Noise Monitoring — Common Questions
New Jersey has a statewide noise code (N.J.A.C. 7:29) that sets limits of 65 dB(A) day and 50 dB(A) night for commercial and industrial sources at a residential property line, but construction and demolition noise is generally regulated at the municipal level through NJDEP-approved ordinances based on the state Model Noise Control Ordinance. Those local ordinances set construction hours and levels, so confirm the specific rule for your municipality with the authority having jurisdiction or NJDEP.
The SV 307A is a Class 1 sound level meter certified to IEC 61672 with octave-band analysis to IEC 61260 — standards closely aligned with the ANSI specifications New Jersey's code references — which makes it well suited to the state's A-weighted and octave-band criteria. Note that official enforcement measurements in New Jersey must be taken by an NJDEP-certified Noise Control Officer; the SV 307A gives consultants and contractors professional-grade, continuous data to document conditions and support that process. Confirm certification requirements with the authority having jurisdiction.
Long deployments are where remote verification matters most. The SV 307A pairs a patented dual-microphone system check with a built-in sound source for manual or automated verification, so you can confirm the measurement path without a site visit, and data stays available through SvanNET for the life of the project. A built-in 4G modem sends SMS and email alerts the moment a threshold is exceeded.
