General Noise Measurements & Surveys
For any existing activity, noise monitoring can record the actual noise levels to prove compliance with regulatory requirements. Environmental Noise Control, Inc. provides a range of noise measurements & surveys, including short-term, long-term, semi-permanent or permanent. ENC’s professionals can configure its large inventory of Type 1 & Type 2 sound monitoring equipment to suit the requirements of any sound monitoring project.
Many cities require ambient sound level measurements & noise management plans as part of the permitting process for industrial, commercial, oil and gas, and environmental works. ENC conducts ambient sound level surveys to monitor existing noise levels before the project is underway. Typical ambient sound level surveys last 24 or 72 hours but can be customized to any length of time to satisfy any city permitting requirements.
Before the activity begins at a proposed location, ambient sound levels are measured to establish non-operational or baseline sound levels. Many noise ordinances use the measured ambient sound levels to calculate allowable operational sound levels. For operations that have already begun, ENC offers operational sound level measurements. Operational sound measurements can be used to verify compliance with allowable operational levels and demonstrate the noise impact of the project operations in the surrounding area.
ENC’s technicians will deploy the meter at a predetermined location, ensuring the best monitoring position is selected for the project. We can deploy web-based meters to provide real-time noise, vibration, and weather data accessible anytime via a web browser. Utilizing countless hours of noise monitoring worldwide, ENC will be able to customize a noise monitoring solution to meet your needs.

Frequently Asked Questions Abut Noise Measurements & Surveys
What Is an Ambient Survey, and Why Is It Required?
An ambient survey measures the existing noise levels at a site before project activity begins. Many cities require ambient survey data as part of the permitting process for industrial, commercial, oil and gas, and environmental projects, since those levels are often used to calculate allowable operational sound levels.
How Long Does an Ambient Survey Take?
A typical ambient survey runs 24 to 72 hours, though ENC can customize the duration to satisfy specific city or agency permitting requirements.
What's the Difference Between an Ambient Survey and an Operational Sound Measurement?
An ambient survey is conducted before activity begins to establish existing, non-operational noise levels. An operational sound measurement is taken once work is underway, to verify compliance with allowable levels and document the project’s actual noise impact.
What Equipment Does ENC Use for Noise Monitoring?
ENC configures Type 1 sound monitoring equipment to match each project’s requirements. For real-time visibility, we can also deploy web-enabled meters that provide live noise, vibration, and weather data through a web browser
Can Noise Measurement Data Be Used for Reports or Modeling?
Yes. Data collected during ambient and operational surveys feeds directly into noise reports and predictive noise impact modeling, giving project teams documentation they can bring to permitting agencies or community meetings.
Does ENC Offer Short-Term and Long-Term Monitoring?
Both. ENC’s surveys can be configured as short-term, long-term, semi-permanent, or permanent monitoring, depending on the project’s regulatory and operational needs.
