Wearable technology seems poised to take over next-generation electronics, yet most wireless communication techniques are not up to the task. To tackle this issue, scientists from the Tokyo University of Science, Japan, delved deep into human-body communications, in which human tissue is used as the transmission medium for electromagnetic signals. Their findings pave the way to more efficient and safer head-worn devices, such as binaural hearing aids and earphones.
Loudness is a subjective attribute of sound that allows us to place it on a scale going from soft to loud without relation to any physical measure. As such, loudness can be affected by background noise, the nature of the noise or music spectrum, the degree of vibro-tactic response, and even your mood.Read More
