 Part 1: Bryan Ellis is a Respiratory Therapist and a Registered Sleep Technologist with decades of experience, operating a physician and primary care-referred sleep diagnosis and therapy center. Bryan discusses insomnia of several types, sleep related breathing disorders, and sleep apnea. He  identifies mechanical problems with sleep, and the many issues that we have with quality of sleep, causes, and remedies. Bryan describes the process of sleep study and related care, and the sleep study environment as well as insomnia vs. respiratory and mechanical sleep issues. Sound and memory come into play. Bryan describes sleep onset insomnia and sleep maintenance insomnia and the distinctions of sleep cycles and stages as well as sleep paralysis. Brain wave frequency responses and ranges determine sleep stages, in extremely low frequency wave patterns, determined by EEG (electroencephalogram). Bryan describes how sound wave research is being done related to memory retention and access, using low frequency sound and pink noise input to the human brain. This fascinating research is leading to memory improvement and may play a role in the treatment of brain disorders of aging. Further discussion details acid reflux and its role in sleep apnea, as well as diabetic related sleep disorders. Bryan will return for a second part at a later podcast.

 Part 2: Amy and Jay Fisher discuss the Clovis Music Festival with future guests and information. Old, vintage electrical test equipment is described, and the need for testing, analysis, and repair of the analog studio equipment. Jay describes repairing and re-coning of early 1950s Altec 602-B monitor coaxial speakers. Altec 604 speakers were a recording studio standard, the basis of Altec’s most popular monitor speakers. Jay details linear air motors which are the basis of speakers, and basic electrical theory. The role of air movement is critical to sound reproduction. Voice coils, magnets, signal, and vibration reproduction creates the sound we hear. Jay describes alignment of the voice coil, magnet clearance, spider, cone, and speaker rebuild and assembly. Hybridization of the vintage analog studio with modern digital equipment is critical for operation.
