Imaginez l’achat de votre première maison et l’enthousiasme que vous éprouvez à enfin devenir propriétaire. L’anticipation de la planification, l’organisation du déménagement et la décoration de votre nouveau foyer selon votre propre style ne sont que quelques-unes des sources d’impatience. Cependant, que se passerait-il si votre foyer de rêve devenait de façon soudaine et inattendue votre cauchemar? Au lieu d’accrocher

How should hearing aids be set for classical music?

Marshall Chasin
What a good question!  I am actually asked this question often during a presentation I give, and it is usually raised after I talk about the unique requirements of string instrument players. My own clarinet and  a violin can generate rather similar looking spectra- they both have much of their energy in the lower frequency region and, like the long-term

Maybe taking the hearing aids off is not such a good idea after all….

Marshall Chasin
In several previous blogs I wrote about a strategy where a musician, or a person listening to music, should simply remove their hearing aids.  Well – maybe I was wrong. Here is the story- at least up to now.  Most modern digital hearing aids are limited when it comes to being able to handle the louder inputs associated with music.

“I’m an analog junkie!”

Marshall Chasin
“I’ve had analog hearing aids for years and my banjo sounded great.  They broke recently and I am now trying my fifth set of digital hearing aids.  They distort the sound of my music and nothing that the audiologist does seems to help.  I am not sure who is more frustrated- me or my audiologist!”   This is a common complaint

Les atténuateurs de bruit en bref

Marshall Chasin
Par Tim Kelsall Presque tous les règlements du monde sur le bruit, y compris celui de l’Ontario, stipulent dans des mots similaires « que l’employeur doit prendre toutes les mesures nécessaires afin d’assurer que les travailleurs ne soient pas exposés à un bruit qui dépasse la limite maximale, sans exiger des travailleurs qu’ils portent et utilisent du matériel de protection

Thoughts on 1 way vs. 2 or 3 way… IEMs

Marshall Chasin
If you ever order in-ear monitors, or IEMs, you are immediately confronted with a major decision:  Do I choose a single-way (one loudspeaker) IEM like a hearing aid, or a 2-way system?  What about a 4- or 5-way system?  Current IEMs have up to five different outputs that can be configured to carry bass sounds (sometimes through more than one

Is the French horn really that much more dangerous?

Marshall Chasin
Anyone who follows the Internet frenzies about any number of topics or reads blogs or even old-style paper newspapers could not help noticing that the past week has seen tons (tonnes in Canada) of coverage about an old topic that has been revisited.  Some of the coverage is valid and other aspects are silly. The valid part is that ALL

LRADs, Hearing Aids, Trumpets and Loudspeakers

Marshall Chasin
Several years ago I was asked to be an expert witness by the Canadian Civil Liberties Association who were contemplating an action against the local police services board regarding an upcoming G20 meeting in Toronto.  The police services board was considering using Long Range Acoustic Devices, or LRADs, as a crowd control device.  LRADs are loudspeaker systems on steroids and

Ray Dolby Passed Away Late Last Week

Marshall Chasin
On Friday Sept 13, 2013, Ray Dolby passed away.  With the passing of Dr. Bose several months ago, the year 2013 was not among the best for the audio industry. I met Ray Dolby at an Audio Engineering Conference (AES) in Los Angeles about 20 years ago and it was my least-cool life moment. After being introduced, I proceeded to
