After 140 chickens reportedly died at a poultry farm in Uttar Pradesh’s Sultanpur following loud DJ music throughout a marriage procession, the incident has reignited issues across the influence of noise air pollution on animals.
The police instructed The Indian Specific that autopsy findings urged the birds died of coronary heart failure linked to acute stress.
Reiterating the identical, Dr Vinod Sharma, Head of Veterinary Providers and Director at DCC Animal Hospital, explains that birds are extremely delicate to sudden environmental disturbances, particularly when stored in confined farm settings.
Can loud music set off coronary heart failure in chickens?
“Sure, it’s medically potential,” says Dr Sharma. “Birds usually have listening to sensitivity thresholds much like people in relation to bodily sound harm. Nonetheless, due to their smaller physique measurement and really excessive metabolic fee, they could be extra weak to acute stress reactions.”
He factors to documented incidents in India the place poultry deaths have been linked to loud DJ music throughout wedding ceremony celebrations. “In each 2021 and 2026, forensic examinations reportedly concluded that the chickens died on account of coronary heart assaults triggered by acute stress from intense noise publicity,” he says.
In keeping with Dr Sharma, loud noise acts as a sudden shock stimulus in birds. “The physique instantly enters a ‘fight-or-flight’ mode. This triggers a surge of stress hormones akin to corticosterone, sharply growing coronary heart fee and blood stress. In excessive conditions, this will result in cardiac arrest, shock, or sudden collapse,” he explains.
Why are poultry birds particularly weak?
Not like wild birds that may fly away from disturbances, poultry chickens are often housed in enclosed sheds with restricted motion. “When extraordinarily loud sound enters such confined areas, the birds can not escape the stressor. Panic spreads quickly across the flock,” says Dr Sharma.

He explains that the issue is not only about quantity but in addition suddenness and period. “Noise above 120 decibels can bodily harm delicate interior ear constructions in birds, very like it does in people. However extended publicity, even at decrease ranges, can create persistent stress and physiological harm.”

How loud noise impacts a hen’s physique
Dr Sharma says extended publicity to high-decibel environments impacts birds in a number of methods:
Hormonal disruption
“Fixed stress elevates corticosterone ranges and should even alter reproductive hormones,” he says. “This impacts development, replica, and total well being.”
Listening to harm
In keeping with Dr Sharma, research have proven that extended sound publicity can harm cochlear cells and quickly impair listening to. “Younger egg-laying birds are sometimes extra prone to acoustic trauma than broiler chickens,” he notes.
Weak immunity and organ stress

“Noise stress can scale back antioxidant capability and immunity, growing irritation within the physique,” says Dr Sharma. “We additionally see stress-related modifications in markers associated with liver and kidney function.”
Warning indicators of extreme noise stress in birds
Farmers can usually establish stress in poultry via behavioural modifications, says Dr Sharma.
“Birds uncovered to extreme noise might all of the sudden huddle collectively, panic, cease grooming themselves, or turn out to be unusually aggressive,” he explains. Elevated feather pecking and chaotic motion inside sheds are additionally widespread warning indicators.
Younger chicks might emit misery vocalisations that point out anxiousness throughout the flock. “Decreased feed consumption, poor development charges and elevated stress hormone ranges are additionally main indicators that the birds are below stress,” he provides.

Can noise completely have an effect on poultry farming?
In keeping with Dr Sharma, even when noise publicity doesn’t straight kill birds, it may possibly nonetheless considerably have an effect on farm productiveness. “Continual stress from loud environments can scale back egg manufacturing, stunt development, and disrupt pure sleep and feeding cycles,” he says. “In deadly instances, sudden cardiovascular shock mixed with disruption of circadian rhythm — particularly throughout resting hours — might turn out to be lethal.”
He provides that poultry welfare is intently tied to sustaining a steady and calm setting. “Farmers usually give attention to meals and illness management, however environmental stressors akin to noise air pollution are equally necessary,” he says.
