Getting the right hearing aid could be easier with a new device that "listens in" on your daily noise exposure. It's called the Octicon's Sound Activity Meter, or SAM for short. It's a computer that's no larger than a lapel pin. Patients wore SAM for a week. So all their daily listening conditions can be measured for sound pressure in crowds or private situations. Then, the acoustics are analyzed by an audiologist. So finally, a hearing aid can be programmed to best address the different listening needs.
Hazmat suits protect military personnel and first responders from dangerous chemicals and more. But while they keep out the bad stuff. They hold in one thing that's dangerous... heat. So now researchers at the University of South Florida are turning up the heat to see which materials work best. In an environmental chamber, study participants walk on a treadmill, while being monitored for temperature changes. Ultimately they hope to learn which fabrics allow wearers to heat and cool themselves without risking exposure to outside hazards.
