In an industry first, an independent testing lab has documented the amazing broadband isolation provided by Sensaphonics custom-fit earpieces.<\/p>\n

Michael & Associates is an independent psychoacoustics test laboratory located in State College, PA and headed by Kevin Michael, Ph. D. According to its report dated April 13, 2017, Sensaphonics custom-fit earpieces showed exceptional isolation, averaging 34 dB attenuation across all frequencies in octave-band testing. The earpieces attained an amazing 45.5 dB average isolation at 8 kHz and, even more impressively, achieved 29.6 dB or greater isolation in the difficult-to-block low frequencies.<\/p>\n

This study is notable as the first time any custom IEM manufacturer has published verified isolation figures from an independent scientific test laboratory.<\/p>\n

There was nothing theoretical about these measurements; no dummy heads were involved. Michael & Associates measured isolation for 10 subjects across 9 standard octave-band frequencies from 125 Hz to 8 kHz, on 3 separate occasions. All attenuation measurements were taken during live listening tests, using American National Standards Institute specifications \u2013 specifically, ANSI S3.19-1974.<\/p>\n

Here are the overall attenuation results across all subjects:<\/p>\n

The statistical standard deviation for test measurements ranged from 3.2 to 4.5 dB, indicating excellent consistency of measurement despite the inevitable differences in fit and insertion technique among the test subjects.<\/p>\n

All study participants wore actual Sensaphonics custom earpieces, made from their proprietary formula of medical-grade soft silicone. Earpieces were made by the Sensaphonics manufacturing laboratory from ear impressions taken according to company specifications.<\/p>\n

Sensaphonics is a strong proponent of evidence-based audiology, designing outstanding audio products that help preserve and protect the hearing health of musicians, their technicians and fans. Superior broadband isolation, as documented in this study, creates a lower noise floor, allowing the monitor feed to be heard more clearly at lower levels.<\/p>\n

\u201cThese test results prove without a doubt that our earpieces provide superior broadband isolation,\u201d says Sensaphonics President, Dr. Michael Santucci. \u201cOur combination of proprietary soft silicone formala, deep ear impressions, and well-trained, highly experienced lab technicians consistently results in maximum broadband isolation and comfort that no other custom IEM manufacturer can match.\u201d<\/p>\n

Michael & Associates is an independent psychoacoutistics test lab, accredited by the National Institute of Standards and Technology (NIST) National Laboratory Voluntary Accreditation Program (NVLAP), Lab number 100427. These accreditation criteria encompass the requirements of international standards ISO 17025.<\/p>\n
