Various methods of assessing noise, loudness, and noise annoyance are reviewed and explained; sources, types, and intensities of traffic noise are noted; typical means of abatement and attenuation are described; design criteria for various land uses ranging from low-density to industrial are suggested and compared with the results of previous BBN and British systems for predicting annoyance and complaint; and a design guide for predicting traffic noise, capable of being programmed for batch and on-line computer applications, is presented in form suitable for use as a working tool. A flow diagram describes the interrelationships of elements in the traffic noise prediction methodology, and each element is discussed in detail in the text. The text is presented of a tape recording that takes the listener through a series of traffic situations, with such variables as traffic distance, flow velocity, distance, outdoors and indoors, and presence or absence of absorbers and attenuators.

An exhilarating and emotional LGBTQ story about the growing relationship between two teen boys, told through the letters written to one another. For fans of Aristotle and Dante Discover the Secrets of the Universe and I’ll Give You the Sun. Thrown together by a zealous English teacher's classroom-mailbox assignment, notorious scrapper, Adam "Kurl" Kurlansky, and Jonathan Hopkirk, a flamboyant Walt Whitman wannabe, have to write an old-fashioned letter to each other every week. Kurl is a senior, an ex high school football player, held back a year, while Jo is a nerdy, out tenth grader with a penchant for vintage clothes and a deep love for poetry. They are an unlikely pair, but with each letter, the two begin to develop a friendship that grows into love. But with homophobia, bullying and familial abuse, Jonathan and Kurl must struggle to overcome their conflicts and hold onto their relationship, and each other.
