Hear The Music

A performance stage is an amazing piece of architectural and acoustic design.  All locations on the stage need to be visualized from as many points in the audience as possible, and the sound level emanating from every part of the stage needs to have similar characteristics.  Very soft “pianissimo” sounds need to be audible, and very loud “fortissimo” sounds needs

The Weber Law (pronounced VEY-ber) has been around for about 175 years.  Also called the Weber-Fechner (pronounce FEK-ner) Law after one of his students gave it its mathematical underpinning, this is a law that attempts to summarize some of our perceptual attributes, such as loudness.  Simply put, the Weber Law states that the just noticeable difference is a constant ratio

The ER-15 earplug was the first to have uniform attenuation and it has been commercially available since 1988.  Its sister earplug, the ER-25 which is more appropriate for drummers and other percussionists reached the marketplace in 1992.   Since that time, the ER-15 earplugs have become the mainstay of hearing loss prevention for those in the performing arts.  More recently other

Every rocker I have ever met (and I go back to the 60s) says that rock and roll needs to be loud.  They are absolutely correct.  To truly enjoy rock music one needs to involve all parts of the brain that respond to the visceral rush of loud music- this ranges from the Amygdala, to the Cerebellum, from the hypo-campus

Since David Kemp’s seminal article in 1978 on “Kemp’s echo”, otoacoustic emissions (OAEs) have been shown to be very useful clinically, despite the difficulty I have in spelling it correctly.  Other than for infant hearing screenings OAEs appear to demonstrate hearing pathology long before an audiometric loss is found.  That is, it takes a significant amount of cochlear damage to

Other than the title being a great joke (at the expense of our brass colleagues), there is some semblance of truth to it. Musicians (i.e. everyone in the orchestra) sit downwind of the trumpets and frequently have to bear the brunt of loud blasts on a regular basis. Other than sticking a sock in the trumpet bell, what can be

Welcome to part 3 of the acoustics of musical instruments (or as musicians would say, part C#)… actually I am sure that they wouldn’t say that- just trying to be funny. In the first of this blog series on the acoustics of musical instruments we discussed quarter wavelength resonator instruments such as the clarinet, and the brass section.  Clarinets have

This is a continuation of last week’s blog on the acoustics of musical instruments.  Last week we talked about quarter wavelength resonators and these are typically the clarinet and the brass instruments.  This latest blog is about the exciting half wavelength resonators- vocalists, strings, sax, flute, oboe and the bassoon. Our vocal chords are tightly held at both ends of

This will be the first of a three part blog on the acoustical bases of musical instruments.  The other two parts will be called Part B flat, and Part C sharp… a bit of music humor there…  Understanding how some instruments work help us to understand some of the comments and complaints from our hard of hearing clients.  It also

I always am amazed by how much the study of music and musicians teaches me about basic audiology.  One of the first things we learn in our first course on noise and its control in school is that the audiogram for noise exposure should be symmetrical.  Asymmetries in the audiogram are most likely related to non-noise etiologies such as the
