Noise Survey Services from Technomax can help the customer identify:
- Places where employees may be exposed to harmful noise levels
- Types of machinery and equipment that generate harmful noise levels more than the normal
- Risk related to employees due to high exposure to harmful noise levels
- Measures that would help in bringing down the high-level noise exposures to accepted levels
- Effect on level of noise from operational changes
- Variation in noise levels under different conditions of the same operation
Advantages of Noise Survey
Carrying out regular noise 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, and 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.
Helps you 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.
- Continuous monitoring of machineries across plants and operation/production floors
- Long-term noise level monitoring
- Noise zone level survey and categorization for existing and newly commissioned vessels, including hearing protector recommendation for new vessels
- Noise survey and zone categorization for industries as per ISO and OSHA for containing sound levels within the allowed limited at workplaces
- Noise forecasts for manufacturing and power plants for commissioning
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.
At Technomax, we work with safety managers, plant engineers, and industrial hygienists to control noise pollution. Conducting surveys is often the first step in handling harmful noise exposure of employees. Over the last decade, we have entered into long term partnerships with manufacturers and service providers, allowing us to provide superior service to our customers regardless of industry or size. Our noise survey services help companies identify hazardous equipment and locations for harmful noise, protect employee’s health, and meet all regulatory compliant requirements.
Our highly trained and skilled technicians will help you to maintain the safety standards of your facilities and employees with swift and reliable noise surveys. Today, with a presence across the Middle East regions, we are able to support many organizations, helping them to define and maintain the approved sound levels at the workplace and ensuring good employee health.
