Noise survey is mainly performed to identify the level of noise in manned space to improve personnel performance and to facilitate communication, sleep, personnel safety and comfort. We, DNV Approved Noise experts provide highly accurate and professional noise assessment and noise measurement services for industries worldwide. We have years of experience and an affordable team who can help you anywhere specialized in all aspects of environmental, Occupational and industrial noise.
Noise is commonly measured in decibels (dB).For peak sound level measurement the C-weighting is used, expressed as dBC. Sound levels in terms of dBA have been in use in B.C. to describe occupational noise for about 30 years. However, with occupational noise, we are concerned with workers’ noise exposure. Noise survey is getting increased attention over offshore and onshore. High noise level leads to hearing impairment, hypertension, ischemic heart disease, annoyance, and sleep disturbance. Changes in the immune system and birth defects have been attributed to noise exposure.

TYPES OF NOISE MEASUREMENTS
- Short or long term monitoring
- Noise surveys to determine existing noise levels
- Noise measurements can be used for noise reports and noise modeling
- Can be customized for your project’s needs
- Web-based monitoring available
- Ambient Sound Level Surveys
- Operational Noise Level Analysis
- Code Compliance Surveys
SHORT OR LONG TERM MONITORING
- The primary goal of long-term monitoring (LTM) is to understand how contaminant concentrations (usually in groundwater) change over years.
- In contrast, short-term variability is the event-to-event change in concentrations that are unrelated to the long-term trend.
WEB BASED NOISE MONITORING
- Real-time (data) monitoring is the streaming of continuously updated zero-to-low latency information.
- Real-time monitoring is used in many fields to enable quick reaction to momentary events.
- Real-time monitoring provides constant information to make up to date informed decisions and see trends as they develop.
AMBIENT SOUND LEVEL SURVEYS
- Ambient sound level surveys last 24 or 72 hours
- It can be customized to any length of time to satisfy any city permitting requirements.
- Measurements are taken before activity begins at a proposed location to establish non-operational, or baseline, ambient sound levels.
EMPLOYEE NOISE COMPLIANCE
A typical approach to assess employee noise exposures and the related complaints may include:
- Sound level measurements, both instantaneous and integrated
- Noise dosimetry on employees
- Octave band analysis
- Evaluation of variables
- Sound level mapping
- Data analysis, including noise levels
- Recommendations for controls to reduce or eliminate exposure
