Why Is A Home Theatre System Marketed As A 5.1 System Rather Than A 6 System Even Though There Are 6 Loudspeakers?
While this is not necessarily a question that an audiologist may ask, it summarizes much about room acoustics and speech acoustics.
Is Someone with a Hearing Loss More (or Less) Susceptible to Future Hearing Deterioration from Loud Than Those with Normal Hearing?
One’s initial gut feeling is that if there is already cochlear damage, then this would increase the chances of further hearing difficulty when compared with someone with normal cochlear function, given the same noise exposure. And shouldn’t that person therefore be counselled to double up on their efforts to wear hearing protection?
Message from the Editor-in-Chief
Definition of a Hearing Aid Whether we are dealing with high-tech hearing aid terminology where band means something different than filter, or lower-tech phrases such as hearing impaired and hard of hearing, definitions can be quite important. In this issue of CanadianAudiology.ca, Gael Hannan tackles the hard of hearing vs. hearing impaired issue — a…

The Easy and the Hard Part of Controlling the Acoustics Of Rooms
From time to time, audiologists are asked about strategies (and products) that can be used to reduce the echoes in rooms in hopes of improving speech intelligibility or to “flatten” the room’s acoustics for music listening and playing. Other than seeking out the assistance of an acoustic or audio engineer (which actually can be well-worth the expenditure), this is a primer on how sound behaves in a room, and how it can be modified. An audiologist may be approached by an “audiophile” who has done a spectral sweep of a room and noticed an unwanted resonance at 120 Hz or 130 Hz, for example. How can we best respond to this inquiry?
The Benefits of Linear Frequency Lowering for Music
Successful approaches for preserving harmonics in music programs can retain the same overall sound of music for people who are hard of hearing.
A Quick Test For Cochlear Dead Regions in Those With a Unilateral Sensori-Neural Hearing Loss and Also to Check if Your Loudspeakers Are Working Well
Several “hearing tests” can now be performed in the quiet of one’s own home. These are predominantly threshold-based tests and are typically limited by the environmental condition of the test room or by the asymmetry of unmatched earphones or loudspeakers commonly used by the public.
Using Bluetooth (And Personal Hearing Aids) for Live Music Performance
Chasin and Morris investigate the common question from performing musicians who wear hearing aids with Bluetooth wireless transmission enabled regarding if they can use their personal amplification as in-ear monitors.

Musical Pathways and Roads
Musical Roads, as the name suggests, are roads that can “play” a song while you are driving on them. The first report of a musical road was in 1995 in Denmark.
