Advanced Functional Materials, EarlyView.This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

This session will introduce participants to the principles of measurement, analysis, and control of environmental noise. Topics will include the selection and operation of sound level meters, statistical descriptors, ordinances and regulations, standards, propagation modeling, and sound barrier applications. No prior experience with environmental noise

Abstract Noise contamination can be defined quite simply as unwanted sound. At high sound pressure levels it can cause temporary and/or permanent losses in our capacity to hear and/or understand speech and in our ability to hear and enjoy music. At lower sound pressure levels it can still be a significant environmental sensory stress.

The effects of environmental noise were estimated from automatic computer-assisted analyses of voice samples. Signals consisted of a live voice sample and a synthesized triangular waveform. Noise was generated from a personal computer fan. Six different A-weighted signal-to-noise [S/N(A)] conditions were created for the live voice and synthetic signal—

An environmental noise monitor has been designed, constructed, and tested for the U. S. Environmental Protection Agency. The system includes a Brüel & Kjaer 4921 outdoor microphone system, a Wang 600-14 computing calculator as the digital controller and statistical analyzer, and a Nagra SJ tape recorder for analog recording.
