Period. ORPHEUS ASCENDS The pursuit of my passion, excellent acoustics, has inspired an audacious change at Orpheus Acoustics. After eleven years of working alone, I have joined the superb architectural acoustics firm Acoustic Dimensions , with offices in New Rochelle New York, Coventry England, and in Dallas Texas. I still maintain my Lancaster, Pennsylvania office, and thus retain proximity to my Pennsylvania (Maryland, New Jersey, and Virginia) clients. You can still reach me at my direct number: 717-291-9123. All of my new work is done through Acoustic Dimensions. I will be directly involved with new projects that involve my old clients. This frees me up to focus on what I love to do and do best: architectural acoustics design. Working with the creative, knowledgeable and experienced acousticians, sound system designers and support staff at Acoustic Dimensions will constantly improve the quality of my work for you. In addition to their deep expertise in room acoustics design and noise control, the Acoustic Dimensions team includes some of the world's foremost sound system designers. Principals David Kahn and Nick Edwards developed many of the seminal ideas behind the Myerson Symphony Hall in Dallas (the first great modern concert hall and still one of the best in the world. Ron Eligator has over 20 years practical, hands-on experience in projects ranging from critical broadcast and recording environments to large performance and entertainment spaces. Craig Janssen is revered in the sound system word. He was on of the first to use the now-ubiquitous line array to provide sound-system clarity in reverberant spaces. This is awe-inspiring company.

Mike Nixon 1937 - 2007 NEWS FLASH click here for reports Mike Nixon Essay What's Wrong with our Classrooms? Childhood is a time of intensive, continuous learning. Both inside and outside the classroom, children practice and develop their social, intellectual and communication skills in a variety of situations. The classroom experience is an opportunity to focus on these critical skills in a controlled environment and provide the stimuli needed to help a child realize his or her full potential. One of the corner stones of a child's early education is the development of language skills. An instinctive grasp of phonetic structure and grammatical rules comes about only through repeated exposure to clear, unambiguous auditory interaction with parents, teachers and peers. Too often such interaction is corrupted or inhibited by the acoustical environment in which it takes place.

Sponsored Links Abatement and Distance from Source The disruption of sound pressures waves which reduces the noise is called attenuation Acceptable dBA Levels Guidelines for acceptable noise levels in terms of dBA for different locations. Acoustic Calculation of Ventilation Systems A procedure for acoustic calculation of noise in ventilation systems Blade Dampers and Noise Generation Noise generated in blade dampers Blade Pass Frequency - BPF The noise level intensity varies with type of fan Calculate Decibel The logarithmic decibel scale is convenient when calculating resulting sound power levels and sound pressure levels for two or more sound or noise sources. Classification of Noise Reduction Silencers Noise can be eliminated with reactive silencers, diffuser type silencers, active silencers and/or dissipative silencers Comparing Noise Criteria Comparing Noise Criteria (NC), Noise Rating (NR), and dB(A) Daily Noise Dose Level Daily noise dose level when exposed in periods with different noise levels Decibel Decibel is a logarithmic unit used to describe the ratio of the signal level - power, sound pressure, voltage, intensity, etc.
