Firefighters in high-pressure, high-risk environments face significant mental health risks. This project uses vibroacoustic therapy, developed through research, to relieve stress. The design focuses on professional image, high-stress routines, and ergonomics.

This project initially analyzed existing solutions like the buddy system and psychological counseling but found them inefficient. First responders value their professional image and may fear stigma or job loss if they speak out. The effectiveness of psychological counseling also varies with individual personalities. Shifting to alternative solutions, we interviewed 20 first responders about their stress management methods, which included yoga, exercising, journaling, breathing, and music. One nurse from New Jersey mentioned using low-frequency music on Spotify to relieve stress during COVID-19, leading us to discover that vibroacoustic therapy could alleviate stress. From an industrial design perspective, we integrated this therapy into our product design. After creating 25 prototypes, expert feedback revealed that initial models were too bulky and conspicuous. Firefighters, concerned about their professional image, do not want to be seen wearing extra gear just to relieve stress. We conducted on-site observational research at the firehouse and found that all equipment is navy blue and worn for all activities. Ultimately, we designed a product to be worn under the uniform, maintaining a professional appearance and supporting daily activities without drawing attention.

This product integrates low-frequency vibrations. According to Dr. Lee Bartel, University of Toronto Professor Emeritus and expert on the effect of sound on the body and brain, research shows that vibroacoustic therapy, through low-frequency vibrations and music, enhances blood circulation, reduces stress, alleviates insomnia, and promotes relaxation and calmness. These low-frequency vibrations typically range from 3 to 20 Hz. Initially used to treat Parkinson's disease, this therapy has also proven effective in calming individuals with ADHD. This design is the first to integrate low-frequency vibration devices into wearable equipment for first responders. Through up to five rounds of user testing with low-frequency vibrations, we identified the optimal vibration frequency, position, and intensity. The vibration panels are made from flexible, soft materials, ensuring they do not hinder the wearer's movement when placed inside the vest.

This is a stress-reducing wearable technology designed for first responders, and it appears there are no similar designs currently available. This design has undergone multiple rounds of user testing to refine its effectiveness and usability in the challenging environments that firefighters navigate. The tests revealed that different genders perceive vibrations differently. Therefore, the vest is tailored specifically for both men and women to provide optimal vibrational effects, including the size of the vibration panels, the placement of the vibrations, and the cut of the vest. It also includes adjustable features to ensure comfort and proper fit. The vibration panels are made of flexible and soft materials, so they do not hinder the wearer's movements when placed inside the vest. Additionally, considering ease of replacement and cleaning, the vibration panels can be easily removed and reinserted.
