Big Brother Lives in New Orleans

Marshall Chasin

In their last series of meetings before this most recent municipal election, he New Orleans City Council and Mayor Mitch Landrieu had called for legislation that would in effect decree that no toilets can be flushed in New Orleans; no telephones can be used; no conversations can be held where there are more than four people talking; and no music

Acoustic Levitation

Marshall Chasin

Now, this is a great title. It sounds like something out of the Twilight Zone or a 1950’s Japanese Science Fiction monster movie where Godzilla meets Von Helmholtz. Well, that’s partially correct- it is something from the University of Tokyo in Japan, and the history is well known. It has to do with everything that has associations with wavelength resonances.

Who is Bob Oliveira? – part 2

Marshall Chasin

In part 1 of this series about Dr. Bob Oliveira we talked about the implications of his 1986 patent showing that a piece of tubing must be glued to a silicon earplug to prevent the ear phone from falling out of the silicon plug- low tech but very effective. Without the glue, we would not have people being able to

Who is Bob Oliveira? Part 1

Try this experiment. Poke or drill a hole lengthwise in one of those yellow foam earplugs that are worn for hearing protection. They can be obtained from your local audiologist or even a pharmacy. For those technical people out there, the hole should be about 2.5 mm in diameter. Then place a standard #13 piece of hearing aid tubing through

L’importance de Bluetooth

Marshall Chasin

Par Adam Fitzsimmons Le fait d’avoir eu le privilège de rencontrer des centaines de professionnels de la santé auditive et leurs patients au cours de la dernière année m’a permis d’apprendre plusieurs choses à propos des demandes changeantes des Canadiens malentendants.

Marshall Chasin

This is the last in a four-part series touching on some of the problems associated with selecting the right programming features for a “music program”.

Marshall Chasin

Welcome back from the Christmas break. I hope it was peaceful and relaxing. This is Part 3 in a four-part series that touches on some of the problems associated with selecting the programming features for a “music program”.

Enfin en sécurité – Faire du vélo en ville

Marshall Chasin

Par Ruth Warick À quelle condition feriez-vous du vélo? Ce titre d’un article de mon journal local a attiré mon attention. La plupart des gens répondront qu’il faut avoir les moyens de s’offrir un vélo et tout l’attirail de cycliste et éviter une chute et une blessure à la tête ou ailleurs. Je répondrais probablement de la même manière à

Readers’s Choice 2013: Why are audiologists afraid of musicians?

Marshall Chasin

This post is a Reader’s Choice selection for 2013. Actually audiologists are macho and not afraid of anything. They wear super-audiologist capes when not in the office and fly around unaided like Superman. (Audiologists do not wear their capes in the office since they may snag on expensive pieces of equipment or trip up clients who inadvertently step on
