Every day and night in the neighbourhoods of Lokhandwala, Mhada, Oshiwara, and Versova, residents face an intense and relentless barrage of noise due to ongoing construction activities.

Our story
As a parent, I am faced with the heart-breaking reality of watching my infant struggle amidst this noise. She is unable to sleep during the day, which leaves her cranky and unwilling to feed. Nights are equally chaotic with the sound of trucks, bulldozers, and collapsing structures making rest impossible.

There was one week I won't forget. My daughter had an infection and was prescribed antibiotics that needed to go in with a feed, every few hours, on the clock. But she wouldn't settle. A pile driver two buildings away would start up, she'd startle awake, and then the crying wouldn't stop — not the ordinary fussing, but the exhausted, inconsolable kind that comes from a baby who hasn't slept properly in days. She refused the feed. Half her doses were missed or delayed because there was simply no calm ten-minute window to get her to feed. We sat in our bedroom at 1am with the windows shut, a towel stuffed under the door, watching the clock and watching her cry, and realised we didn't actually know who we were supposed to call — was it the builder's site office, the police, the BMC ward, some pollution board none of us had ever had reason to look up before? That helplessness, on top of an already sick and sleepless baby, is something no new parent should have to go through.

This is not just our story. Many families and senior citizens in these Mumbai communities suffer silently. Infants, like mine, are deprived of their essential sleep, crucial for their growth and development. Elderly residents, who often need a peaceful environment, find themselves trapped in this cacophony. These redevelopment projects, despite their long-term benefits, are making daily life unbearable.

What the noise actually does
WHO guidance: The WHO Guidelines for Community Noise recommend under 30 dB(A) inside a bedroom at night for good-quality sleep, and under 40 dB(A) average night-time outdoor noise (L-night) to avoid adverse health effects. Pile drivers, rock drills, and demolition routinely blow past this — noise measurements at Mumbai construction and Metro sites have recorded 80–102 dB(A), more than double the permitted residential night limit of 45 dB(A) under Maharashtra's own rules.
Infants: Research on newborns (including NICU studies) links noise exposure to disrupted sleep-wake cycles, and measurable stress responses — changes in breathing, heart rate, and oxygen levels — because infants' nervous systems are still developing the ability to self-regulate. Pediatric guidance from the American Academy of Pediatrics specifically flags environmental construction noise as a driver of sleep disruption in young children.
Elderly residents: WHO's noise evidence review links long-term night noise exposure to sleep disturbance, elevated blood pressure, and increased cardiovascular risk — effects that compound in populations, like the elderly, who are more vulnerable and were historically excluded from the "average population" studies noise standards were built on.
Everyone in between: Annoyance, disturbed concentration, and stress-related health effects are well documented at the noise levels our neighbourhoods are exposed to daily.
Under the Noise Pollution (Regulation & Control) Rules, 2000, residential areas are capped at 55 dB(A) by day and 45 dB(A) by night, and construction between 10pm–6am is not permitted without special exemption. The Bombay High Court has repeatedly held that the right to sleep and to a peaceful environment falls under Article 21 of the Constitution. BMC rules already require builders to restrict night work, use noise-reducing equipment, install sound barriers and acoustic sheets, and display complaint contact details on site — but compliance is patchy at best. 

Proof it can work
Mumbai's own Metro-3 precedent: After residents petitioned the Bombay High Court over night-time drilling noise, the National Environmental and Engineering Research Institute (NEERI) recommended physical noise barriers around sites and sound mufflers on equipment. The Court also directed the state to set up dedicated toll-free numbers and a grievance redressal system specifically for construction noise complaints — a model that could be replicated for every large redevelopment project, not just Metro.
New York City: DOB rules require perimeter noise barriers (built to a minimum sound transmission rating) at any site within 200 feet of a residence, school, or hospital, plus "noise curtains" or portable "noise tents" over specific loud equipment like pumps, compressors, and jackhammers — with mandatory noise-mitigation training for site supervisors.
UK practice: Many contractors under the Considerate Constructors Scheme voluntarily use acoustic enclosures and site hoarding rated to reduce noise at the boundary, even where it isn't yet a hard legal requirement.
What actually dampens the noise
For pile drivers, rock drills, compressors, and other heavy equipment, proven mitigation options include:

Perimeter noise barriers / hoarding — solid barriers around the site boundary, rated to a minimum sound transmission class, positioned to block the line of sight between equipment and homes
Acoustic enclosures and shrouds fitted directly around generators, compressors, and pile-driving rigs
Noise curtains and portable "noise tents" thrown over smaller loud equipment like jackhammers and pumps
Quieter construction methods — e.g., bored or pressed piling instead of impact pile driving, which cuts peak noise dramatically
Upgraded exhaust silencers and engine casing insulation on generators and heavy vehicles
Strict enforcement of the existing 10pm–6am ban, with real-time decibel monitoring at site boundaries (as NYC now mandates) rather than relying only on resident complaints
Mandatory display of a grievance contact and site supervisor name/number, and a dedicated toll-free helpline per project, as the Bombay HC ordered for Metro-3

Our ask
We call upon municipal authorities to mandate the use of sound barriers, acoustic enclosures, and quieter equipment at all construction and redevelopment sites, specifically in our densely populated and growing areas — and to actually enforce the night-time construction ban and existing noise limits that are already law but routinely ignored.

If you're facing this right now
BMC 24x7 helpline: 1916 (or the MyBMC Assist chatbot: +91 89992 28999)
Maharashtra Pollution Control Board grievance portal: mpcb.gov.in/grievances
Local police station — noise pollution is a public nuisance offence they can act on immediately
Ask the site to show its NOC and permitted working hours — they're required to display this
It's time for a change. Our infants deserve their peaceful days, and our elderly citizens deserve their restful nights.
