Listening to the Flock: How AudioT Can Help Poultry Farmers
On a North Georgia poultry farm, thousands of chickens are clucking and chirping under the noisy hum of fans. Amongst the chatter, a small device is quietly eavesdropping. “You can tell how chickens are doing just by how they sound,” says David Anderson, a Georgia Tech professor and TSRB researcher who has made a career of listening closely. Anderson’s startup AudioT is proving that some barnyard wisdom is true, using advanced voice analysis and machine learning to monitor chicken health and behavior in real time.
Anderson is no stranger to audio innovation. A professor at Georgia Tech’s School of Electrical and Computer Engineering (ECE), he is an expert in signal processing. Early in his career, he even developed a digital hearing aid algorithm that became a commercial product. But about a decade ago, he turned his expert ear to an unlikely subject — chickens. Farmers have long claimed they can gauge a flock’s well-being just by walking into a chicken house and listening. Anderson wondered if technology could capture and quantify those auditory clues that human ears pick up anecdotally. The result is AudioT’s core idea: using simple microphones and artificial intelligence to translate “chicken talk” into actionable data for farmers.
From Lab to Farm
Years of research at Georgia Tech in collaboration with the University of Georgia laid the groundwork. Early on, Anderson’s team recorded thousands of chicken vocalizations and matched them with the birds’ observed conditions. A key challenge was separating chicken sounds from the clamor of a poultry house — the large ventilator fans, for example, can be louder than the birds themselves. Anderson likened it to picking out a single conversation in a restaurant with a hundred murmuring diners. But once that classic signal-processing hurdle was overcome, the machine learning models could start finding meaning in the clucks.
Within a few years, the algorithms learned to recognize when chickens were experiencing stress by analyzing the flock’s collective chatter. Those early experiments hinted at how much value is hidden in a coop’s ambient noise. For example, temperature swings have a distinct acoustic signature of flock discomfort that the software learned to detect. Chickens also respond audibly to uncomfortable ammonia levels in the air. Meaning levels can be monitored without requiring pricey chemical sensors. “Currently available ammonia sensors are expensive and short-lived,” Anderson explained. “If a system with a few microphones and the right computer algorithms could take over ammonia-detection tasks, it would help reduce costs for the entire industry.” In other words, a low-cost microphone array might do the job of several specialized gadgets. That simplicity and cost-effectiveness are the guiding principles of AudioT’s design.
Hearing the Flock: How AudioT Works
Today, AudioT’s product is as straightforward as it sounds. A handful of small microphones are installed throughout a poultry house, continuously recording the chatter of the birds. The audio feeds into a machine-learning software computer that “listens” for anything unusual. Crucially, the system adapts to the birds’ life cycle — baby chicks don’t sound like adult hens, so the algorithms adjust as the flock grows. The AudioT monitor is designed to be as easy to use as any appliance on the farm, requiring minimal effort or technical know-how from the farmer. Unlike camera-based systems, microphones work even in darkness or dusty air to monitor the birds 24/7 without disturbance.
When something unusual happens in the barn, AudioT picks it up. The system recognizes specific “auditory shapes” — patterns in sound linked to known issues. A sudden burst of harsh, scratchy clucks might mean the birds are alarmed by a predator or an intruder. A spike in coughing could signal an early respiratory disease outbreak. If a feed auger runs empty and squeals, or a water pump fails, the change in background noise stands out and triggers an alert. When AudioT’s algorithms detect such an anomaly, the farmer gets a notification on their phone or computer, indicating the location of the problem. AudioT gives growers a permanent, tireless set of ears in every barn.
The implications of this technology are huge for poultry farmers. Broiler chickens are the nation’s most-consumed animal protein, and Georgia produces 15% of all U.S. broilers — more than any other state. Poultry is a $28 billion-a-year cornerstone of Georgia’s economy, supporting over 80,000 jobs. But profit margins in chicken farming are razor-thin, and a single disaster can wipe out a flock. Disease is a constant worry – between 2022 and 2023, nearly 60 million U.S. birds were lost to a virulent avian flu outbreak. Heat, stress, or equipment failures can also kill thousands of birds quickly. In this high-stakes environment, catching problems early is crucial, which is precisely what AudioT aims to accomplish.
AudioT’s approach has drawn national attention. The startup has been backed by funders from McDonald’s to the National Science Foundation and poultry giants like Tyson Foods. These investments have helped Anderson’s team test and refine the system on commercial farms, aiming to scale up low-cost, automated welfare tools for a shrinking agricultural workforce. In short, many in industry and research believe listening to chickens could reshape how we raise them.
For Anderson, seeing his research evolve into a real-world solution has been deeply rewarding. He emphasizes that AudioT doesn’t replace farmers or veterinarians but enhances their awareness. “Think of it as a smoke alarm or a baby monitor for the chicken house,” he says. “It’s there in the background, letting you know when something’s wrong.” With a few well-placed microphones and the right algorithms, farmers gain a powerful new tool that might be the future of poultry care.
