Noise Monitoring & Survey in UAE
Noise monitoring also called noise surveys are conducted to identify areas of harmful levels of noise with the use of special measuring instruments that will allow the initiation of appropriate measures to protect workers who are continuously working in these areas. It is, therefore, an essential component of safety in a number of industries.
What Is a Marine Noise Monitoring and Survey?
A marine noise monitoring and survey is a systematic assessment of sound pressure levels onboard ships and offshore vessels. The survey evaluates noise exposure in accommodation areas, machinery spaces, control rooms, and workstations to ensure compliance with IMO, ISO, and occupational health standards. Excessive noise can affect crew health, operational efficiency, and vessel certification, making periodic noise surveys essential.
Noise surveys should be conducted, especially where employees have to use a high volume tone to one another to be heard even if they are not standing far apart. Some of the most common places where employees need to use high decibels to communicate with each other are in the marine field during ship sailing and operational floors in other industrial fields, plants, airports and so on. We provide marine condition monitoring that detects issues early, reducing downtime and extending engine life.
Technomax provides professional marine noise monitoring & survey services onboard vessels across the UAE and the Middle East, supporting ship owners, operators, shipyards, and offshore companies in meeting Noise Code and international occupational safety requirements. With over 20 years of engineering expertise, we deliver accurate noise measurements, compliance reports, and practical recommendations to enhance crew safety, regulatory compliance, and vessel performance.

All surveys are performed by trained and experienced certified engineers.
Advantages of Noise Survey
Carrying out regular noise monitoring and surveys provides several advantages to companies, mainly, gleaning information which they would not otherwise have access to. There are three types of testing that is conducted:
- Spot readings
- Continuous monitoring
- Long-term monitoring
Spot readings are single readings taken with a handheld device. In continuous monitoring, the meter is installed at a location and measuring is taken at regular intervals, helping to understand the noise trends and variations. In long-term monitoring, the sound is measured in small intervals from 5 minutes to an hour, over several weeks / months to understand patterns of noise pollution in the long term.
Identifies High Risk Areas or Equipment
Any sound above 65 decibels is categorized as noise pollution, and as it goes louder, these sounds can become extremely harmful to the people working in the vicinity. By using the right equipment, we can help you identify the specific areas in your facilities, or the specific machinery or equipment that generate the maximum noise. As per WHO, the acceptable sound level is 55 decibels during the day, and 45 at night. Other standards may apply according to your country or industry, though industrial standards mostly require the noise levels to be 65 decibels or below 75 decibels.
How Noise Monitoring Protect your Employees
The need for measuring the employees’ noise exposure arises when a noise survey indicates the possibility that the employees may be exposed to noise exceeding the noise exposure limits set by noise regulations or the limits set by the company.
Continuous exposure to loud sounds can cause the employees to have headaches, sleep disorders, hypertension, heart issues, buzzing or ringing sounds in their ears, experience partial temporary or permanent hearing loss, and may lead to mental health problems.
By knowing which areas or equipment pose the most risk, the organization can take the appropriate steps to protect the employees who are exposed to such environments. Providing hearing protection like industrial ear muffs, regular breaks or short shifts, using sound proofing materials to reduce noise, training employees to identify hazardous levels of noise, timely reporting of such issues, and so on, are some of the steps we can take to help protect employee’s health.
Adhere to Compliance Regulations
Every country has regulations relating to Employee Health and Safety and protecting them from harmful noise levels is one among them. By conducting regular noise surveys, we can ensure that your organization maintains compliance with international, national, and local regulations as well. ISO, ILO, and OSHA, are some of the most important regulations many industries follow.

How does it work?
A noise level meter is made up of many parts such as power supply, communication system, display system, processor, microphone, frequency weighting, and pre-amplifier. The equipment is calibrated, and the survey is conducted to ensure coverage of noise generation by the usual operations and activities in the daytime, as well as a part of night time activities. At the time of monitoring, the sound level meter measures sound pressure levels.
For spot or one-time readings, our Engineers will hold the meter standing one arm length away from an employee, and hold at the ear level of the employees working in the location with exposure to harmful noise, and test it on the right and left side to replicate the experience of an employee on a typical day. If employees work in environments where the noise levels keep changing all the time, a PSEM or personal sound exposure meter is placed on the shoulder of the employee, which records the noise exposure throughout the shift. For long-term or continuous monitoring, the sound meter is installed in the locations, usually on tripods, where the noise exposure is suspected to be very high. The average noise levels over a certain time period are calculated to determine the extent of harmful noise exposure employees are subjected to.

FAQs
1.What is noise monitoring?
Noise monitoring is the systematic measurement and analysis of sound levels to assess exposure, compliance, and potential health risks. It helps identify excessive noise, protect people, and ensure compliance with occupational and environmental regulations.
2. What are the 4 types of noise?
The four common types of noise are continuous noise, intermittent noise, impulsive noise, and low-frequency noise. Each type affects human health differently and requires specific measurement and control approaches.
3. What are the types of noise monitoring?
Noise monitoring includes environmental noise monitoring, occupational noise monitoring, community noise monitoring, and industrial noise monitoring. These assessments help evaluate compliance, exposure levels, and noise impact in different settings.
4. What is the OSHA standard for noise monitoring?
OSHA sets a permissible exposure limit (PEL) of 90 dBA over an 8-hour time-weighted average. OSHA also requires a hearing conservation program when employee noise exposure reaches or exceeds 85 dBA.
