Researchers at Purdue University have developed an innovative new model of noise-cancelling headphones that work with an integrated app to selectively cancel certain noises while allowing others to be heard clearly. Users can choose which noises to allow through the paired phone app, enabling total customization suited to their exact needs. This technology is tailored for construction workers but can be used by anyone who needs noise-cancelling headphones.

Noise pollution from construction is a major factor jeopardizing occupational health. Over 30 million construction workers are exposed to prolonged noise on a daily basis, which causes discomfort and can often lead to long-term adverse health effects. To combat the noisy environment, many workers choose to wear earplugs or noise-cancelling headphones, but this can create dangerous situations in which workers are left unaware of their surroundings. With this innovative technology, the comfort and safety of workers can be assured in both the long- and short-term.

Technology Validation:

Through a combination of comprehensive research methodologies, including user interviews, competitive analysis, and thematic qualitative data analysis, the project integrates innovative features such as active noise cancellation, ergonomic design, and gamified feedback through a companion app. These advancements demonstrate a practical application of research insights to create solutions tailored to the specific needs of construction workers.

Advantages:

-Customizable and user-friendly

-Effective noise cancellation muffles unwanted or hazardous noise

-Selective noise cancellation allows important sounds, like warnings and alarms, to be heard clearly

-Improved communication in noisy environments
