From Reverberating Chaos to Concert Halls, Good Acoustics is Culturally Subjective

Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play that same flute in the Grand Canyon, and the sound waves will crash against the rock walls, folding back in sonic chaos. The disparity is clear – to the modern listener, the instrument belongs in an auditorium. "Distinct echoes would be totally unforgivable in today's performance spaces," says Steven J. Waller, an archaeo-acoustician. “But, in the past, people sought echoes."

All Sounds Made Equal in Melancholy

Psychoacoustics identifies five basic types of emotional speech: angry, fearful, happy, sad and neutral. In order to fully understand what’s happening with speech perception, a research team at the University of Texas at Austin studied how depressed individuals perceive these different kinds of emotional speech in multi-tonal environments. They will present their findings at the 169th ASA meeting, held this week in Pittsburgh.

School disciplinary actions handed down to students at Utah public schools disproportionately impact American Indian children over all other ethnicities enrolled in the state’s public education system, new research from the University of Utah S.J. Quinney College of Law Public Policy Clinic reveals. Researcher and law student Vanessa Walsh found that although American Indian students comprise the smallest student demographic in Utah, they have the largest percentage of students referred to law enforcement and arrested at school. The rates for disciplinary actions taken against American Indian students are much higher than for white students. Studies show that suspension and expulsion rates are closely correlated with dropout and delinquency rates, and have tremendous economic costs. Referrals to law enforcement and arrests at school are the harshest forms of school disciplinary action and expose students directly to the juvenile justice system. Such students often become part of the “

Using human embryonic stem cells, researchers at University of California, San Diego School of Medicine and Moores Cancer Center and Sanford-Burnham Medical Research Institute created a model that allows them to track cellular behavior during the earliest stages of human development in real-time. The model reveals, for the first time, how autonomic neurons and blood vessels come together to form the neurovascular unit.
