Gurgaon: Although the post-diwali air quality in the city dropped to the worst in this six years, noise pollution saw this diwali reduction in sown housing areas.
According to data from two monitoring stations installed by the state pollution control agency Haryana (HSPCB), DLF-2 (residential area) saw 5.5% dip in this diving decibel level, while in Sohna Road (commercial area), the noise level was almost equivalent With last year’s festival day.
Two stations measure noise in decibels (weight), relative loudness of sound in the air as perceived by the human ear.
Diwali this, the peak noise level is 65.3dB (a) at the DLF-2 station.
The average is 64.2dB (a), the lowest in four years.
The average rate is 71db (a) in Diwali in 2018, 70dB (a) in 2019 and 68dB (a) last year.
At Sohna Road Station, the peak is 81dB (a) Diwali, while the average noise level is 70.1db (a), a slight increase from 70dB last year (a).
It was 71db (a) in Diwali in 2018 and 69dB (a) in 2019.
The noise pollution level was recorded over a six-hour period of this diwali between 61dB (a) and 65.3 dB (a) on DLF-2 and between 68DB ( A) and 81db (a) in Sohna Road.
“Even though Diwali witnessed a surge in air pollution, there was a slight volume of traffic on the road and crackers with low intensity explodes on DLF-2, resulting in a decrease in noise level,” said Ram Niwas, a HSPCB scientist.
This year, like last year, HSPCB has installed a noise meter in two locations.
In comparison, the pollution control agency has installed meters in four locations – DLF-2, Sohna Road, Imt Manesar and Bus Stand – in 2019 and 2018.
Standard CPCB guidelines for pollution noise, which was notified in 2000, recommended no more than 55dB noise In residential areas, 65DB in the commercial area and 75dB in the industrial area during the daytime.
At night, the upper limit of the appropriate is 45dB, 55db and 70db.
It needs more noise monitoring stations with only two areas monitored for noise pollution in Diwali, data is not indicative for the entire city, according to experts.
They suggest that some locations must be chosen to install meters.
“Ideally, more locations must be protected to study noise fluctuations before and in Diwali in the city,” said Sachin Panwar, an air pollution and noise.
“Simply putting the noise meter in an area randomly will not serve the purpose.
Authorities must relate to RWA throughout the city, and through them, educate the population about the impact of noise pollution.
In addition, old Gurgaon and new areas in the city are not represented in the data At present.
Monitoring Stations are only in two locations, which do not provide a fair view of the situation, “Panwar added.
A senior HSPCB official said they planned to prepare a sustainable real-time noise measurement system with digital display boards and centralized networks in four locations.
“We have a plan to install a permanent noise monitoring station in Gurgaon soon.
They will monitor the level of noise continuously all the time,” the official said, adding that HSPCB already has a network of air quality monitoring stations and the possibility of installing noise monitoring stations in the location Same – Sitan Vikas, Teri Gram, Galpahari and Sector 51.
Residents in areas such as Sector 50, 57, 89, 90 and 92 that Ti spoke to say crackers did not seem muted in their neighborhood at night Diwali.
“Crackers began at 7pm at Diwali and continued until 11pm.
We can’t sleep and my husband faced difficulties breathing because of pollution,” said Rekha Aggarwal, a citizen sector 57.
“There is no civil body to monitor the newly developed sector .
Some residents continue crackers that exploded throughout the night, “said Punit Kaushal, a resident of Sector 89.
in areas like DLF-2, MG Road and Sushant Lok, on the other hand, residents said crackers isolated instance.
“I can hear the sound of vague crackers.
Nothing is very noisy,” said Tanvi Nayak, a resident of DLF-2.
