Noise or sound level monitoring or measurement is a process to measure the 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 the 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 Perfect Pollucon Services conducts Noise Testing in the company or home to measure high noise within premises. Actions can be taken once the locations and source are identified which are causing the noise. it helps to keep your employee or family safe from Harmful Noise.

Measurement of Noise Level Using Noise Testing Equipment

Sound/Noise level meter equipment measures noise pollution. It consists of several parts, 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 noise measurement. “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 the increase in noise pollution in recent years, it is recommended to conduct a measurement of noise pollution program on company premises.

Noise level Monitoring & Testing

The answer to the question of how to measure sound lies in Noise level Monitoring or sound Measurement for a particular instance or for 24X7 hrs to analyze trends for better understanding of the 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

Industrial Noise is the loud sound in industries. In general, it is produced, at every stage in the 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, moulding, 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.

B) Non-Industrial Noise Measurement

i)Road Traffic Noise:

Road traffic is the most widespread source of the noise. It is directly proportional to the volume of vehicles. Increasing the population is increasing in 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 Level Monitor instrument (or with noise level data logger) measures the noise level.

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 the 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.
