Multi-channel Compression: Concepts and (Early but Timeless) Results

Jan 20, 2016 | Research | 0 |

The authors look back at a study from 2000 that showed short time constants and a large number of independent compression channels reduced the temporal and spectral contrast of speech when using technology of that period. Additionally, in subjective paired comparisons, long time constants, low compression ratios, and a small number of compression channels were preferred in the investigated technology configuration by normal-hearing and hearing-impaired listeners.

Back to Basics: Linguistics 101 for Hearing Healthcare Professionals

Jan 20, 2016 | Continuing Education | 0 |

The Speech Intelligibility Index (or SII) shows some interesting characteristics. The difference between 340 Hz and 3,400 Hz (coincidentally the bandwidth of the telephone) is fairly similar for continuous discourse, whereas there is a high frequency bias for nonsense syllables. That is, whenever there is a context to speech, there is a greater reliance on lower frequency sounds.

Scientists Uncover New Clues to How Pitch Perception Evolved

Jan 1, 2016 | Research | 0 |

Pitch perception is not a skill unique to humans, say scientists from Johns Hopkins University (JHU), where a recent research study reveals that marmosets, considered to be “ancient” monkeys, appear to use auditory cues to distinguish between low and high notes associated with melody.

Back to Basics: A Discussion on Definitions of Sound

Performance and Preference of an Automatic Hearing Aid System in Real-World Listening Environments

Nov 24, 2015 | Fitting Equipment, Testing Equipment | 2 |

A recent study assessed the capability of Phonak AutoSense OS to provide optimal and preferable listening in three complex, real-life listening environments: 1) A highly echoic room with presentation of speech from behind and noise interference, 2) a running car, and 3) a busy coffee shop. The findings suggest that AutoSense OS not only provides significantly greater ease of use than a manual program, but can also provide optimal hearing in challenging, realistic listening environments.

Back to Basics: A Primer on Equivalent Volume, Impedance, and Couplers for Hearing Aids

Nov 21, 2015 | Continuing Education | 0 |

Dr Chasin discusses how most audiologists (himself included) tend to sweat upon hearing the word “impedance.” Although “admittance” is a much less nuanced word, it can be just as scary. Most audiologists and hearing care professionals would rather hear about the phrase “equivalent volume.”
