Identification. There are many species of salamanders but some of the most toxic are tiger salamanders, spotted salamanders, and the rough-skinned newt. Salamanders excrete milky toxins through their skin when touched or eaten.arshes, ponds, lakes and streams are common areas where salamanders are found during breeding season. Other times they are seen in drier areas such as forests and fields. Salamanders are amphibians, which characteristically breathe through gills, have smooth skin, and produce jelly-coated eggs.
Microphone development as we know it today was distilled from telephone technology, whose roots go back to the mid 1800s. The word âmicrophoneâ was ï¬rst coined by Wheatstone around 1827 and was used to describe a purely acoustic device, like a stethoscope, which he had developed to amplify weak sounds. The word is Greek in origin, with âmicroâ meaning small and âphonâ meaning sound. It was not applied to telephone devices in general, which were instead called âtransmitters,â a practice continued by Western Electric almost until it ceased professional microphone production in the 1940s.
TPF funded 2 years of summer research that allowed Chris to work Dr. Ron Miles who invented the smallest directional microphone. Dr. Miles (a Mechanical Engineering Professor at Binghamton University) needed a student to help him place that microphone into hearing aids and Chris aided in that process with a research scholarship provided by TPF
