Noise Level Monitoring


Noise Level Monitoring

Noise or sound level monitoring or measurement is a process to measure magnitude of Noise in industries and residential area. Data collected from Noise level monitoring & Testing helps us to understand trends and action can be taken to reduce noise pollution. Noise pollution is Low or High frequency sound that can cause/harm the activity of human life. It can be caused by various industrial Machines, Motor Vehicles and Craft etc. Noise Pollution Monitoring process is a part of Environmental Monitoring & Testing as noise pollution is also increasing exponentially in recent years.

What is Noise Pollution?
Noise pollution is unwanted and unpleasant sound which can deteriorate human health and other living organisms present in Environment.

Why to Measure Noise at the Workplace?
At workplace machines, traffic, vehicles create occupational noise. Employees and occupants are exposed to this harmful noise. Due to this occupants can face many health problems such as headache, hearing impairment, hypertension, heart problem, annoyance and sleep disorder. to Avoid this situation DEEPA ENTERPRISES TESTING LABORATORIES conducts Noise Testing in company or home to measure high noise within premises. Actions can be taken once the locations and source are identified which are causing noise. it helps to keep your employee or family safe from Harmful Noise.

Measurement of Noise Level Using Noise Testing Equipment
Noise pollution is measured by Sound/Noise level meter equipment. It consists of several pNoise Level Monitoringarts, mainly Microphone, Pre-amplifier, frequency weighting, Processor, Display System, communication System and Power Supply. dB(A) Leq denotes the time weighted average of the level of sound in decibel on scale A which is relatable to human hearing.

A “decibel” is a unit in which noise is measured. “A”, in dB (A) Leq, denotes the frequency weighting in the measurement of noise and corresponds to frequency response characteristics of the human ear.

Leq: It is an energy mean of the noise level over a specified period.

Noise level Survey schedule is planned in such a way that it covers the noise generation by normal daytime activities i.e. from 08:00 am to 10:00 pm and a part of nighttime activities i.e. 10:00 pm to 12:00 am (at night).

Due to increase in noise pollution in recent years, it is recommended to conduct measurement of noise pollution program in company premises.

Noise level Monitoring & Testing
The answer of the question of how to measure sound lies in Noise level Monitoring or sound Measurement for particular instance or for 24X7 hrs to analyze trends for better understanding of environment. these Processes also used in Noise Impact Assessment (We love to do this 😉 ) by Noise level Testing companies. This process is also called as Noise level Measurement.

To know more about Noise impact assessment.

A) Industrial Noise Measurement
Noise produced by industries is called Industrial Noise. In general it is produced, at every stage in industry by various aspects like welding, hammering, drilling, blowing, running machinery, motors, sheet metal work, lathe machine work, operation of cranes, grinding, turning, fabricating, forging, compressing, breaking, molding, steaming, boiling, cooling, heating, venting, painting, pumping, packing, transporting etc. It creates very serious of large-scale noise problems; significantly affect the working people as well as surrounding people.Industrial noise
B) Non-Industrial Noise Measurement
i)Road Traffic Noise:
Road traffic is the most widespread source of noise. It is directly proportional to the volume of vehicles. Increasing of population is increasing of vehicles and hence increasing of Noise pollution. The major sources of noise in automobiles are exhaust, intake, engine and fan, and tires at high-speed. Noise measurement or sound measurement can be done by noise level monitor instrument (or with noise level data logger).

Traffic Noise Pollution
ii) Residential Noise Measurement
In normal day –to – day activities, various home appliances in our residences produce noise. Some of the major sources are Exhaust Fans, lawn movers, grinders, Fan, Cooling & Heating System, T.V & Music System, motors used for pumping etc.

Noise Level Testing Standards
Limits or noise level standards defined by pollution control board during Day time for Residential Noise < 55 dB and Limits during Night time for Residential Noise < 45 dB

In industry, there are of two types Sound Monitoring & testing or Noise Level Measurement:

- Ambient Noise level Monitoring
- In-plant Noise level Monitoring

A) Ambient Noise Level Testing Standards
Ambient Noise level Monitoring or Noise pollution Measurement within industrial zone at ambient conditions. (e.g. Near Main Gate, Near Canteen, Near Manufacturing plant etc.) As per Central Pollution control Board (as per Factory act 1948):
Limits or acceptable noise level during Day time for Ambient Noise < 75 dB and Limits during Night time for Ambient Noise < 70 dB.

B) In-plant Noise level Testing Standards
In-plant Noise level means Sound level measurement allocated in the plant.As per Central Pollution control Board (as per Factory act 1948) Limits for In-plant Noise level < 90 dB.
