Introductory Note by the Editor
Malcolm Tattersall has kindly offered the opportunity to the Knowledge Base to become an “official” website for his basic research into noise exposure as an issue of occupational health and safety for music teachers. The research was carried out in 2005-06 when the author found that there was very little published information about this issue. It remains current. We are pleased to accept the invitation.
This first article introduces the research. The author provides the following explanation of its structure:
The remaining pages –
– are all side-bars to those two, and Malcolm Tattersall’s introduction which follows below frames the whole lot.
Finally, Noise Exposure of Music Teachers: Links contains a complete list of references as well as another set of links to the articles.
Hans Hoegh-Guldberg, Editor, 21 April 2014.
This group of articles is concerned with noise exposure and potential hearing loss among music teachers and other musicians. The focus is on teachers working with small groups of woodwind students in schools. I hope it will be useful to others — woodwind teachers in the studio situation, and brass, percussion and string teachers in both settings — but have not systematically extended my work to mention all the differences. Non-teaching musicians are further from the focus but may still find my work relevant.
The material began as a single article intended for one of the magazines which serve the Australian music teaching profession but my colleagues’ interest in it encouraged me to make it available on the web even before it was quite finished.
By the time the article appeared (in Music Forum, Vol 12 No 2, Feb – April 2006) the web site had taken on its own life. Containing ancillary material as well as a variant of the final article, it was all subjected to (minor) revision on the basis of my own further research and readers’ comments. In February 2006 it was re-organised for clarity and it remained on my own site, with only minor updates, until the Knowledge Base accepted it in 2014. This introduction was revised at that time and links were again checked and updated but none were added.
Status of This Material
I am an experienced instrumental music teacher with a good background in physics (see ‘The Author’ below) but no qualifications in occupational health and safety. At this stage I am sure that all of my material is essentially correct but I need to stress that (1) situations vary, so that what I am talking about may not apply exactly to any individual teacher, and (2) my figures are not exact, so my results can only be approximations. My approximations are the best I can manage, but do not panic, and do not take any radical action, on the basis of my work alone. Seek more information!
That said, I would not have even begun work in this area if I had found the information I needed was already freely available. As I continued my research I came to believe that no-one had ever published any substantial articles on exactly my topic. There was a reasonably large literature on noise exposure of ‘band directors’ in North American school systems — instrumental teachers, true, but working under quite different conditions — but apparently none (in 2006) on studio or small-group teaching.
Seeking more information will therefore be a matter of exploring the resources on my Links page, which may be helpful but may not apply directly to your own situation, looking for more recent studies, and consulting Occupational Health and Safety staff in your own workplace, who ought to be willing to help but may not know much about noise exposure.
A not-too-technical article which introduces basic concepts of acoustics, noise exposure and legal liability. It then estimates actual exposure of music teachers who work primarily in the small-group teaching situation, relying in part on Approximating Noise Exposure. It was originally the first half of Teaching Strategies.
It suggests teaching strategies to reduce unnecessary over-exposure without compromising the quality of instruction. It is the second half of the original Teaching Strategies; this and Defining the Problem, together with their associated references, are essentially the same as the print version, Reducing the Noise (see Links).
A slightly more technical study of one aspect of the problem: an attempt to refine the exposure estimates by determining the effects of group size, teaching style, room acoustics and the instruments taught.
A check-list of easily observable symptoms.
Argues that a properly designed programme should not expose students to dangerous sound levels, acknowledges that teachers may still be over-exposed, and discusses the pros and cons of earplugs.
A very brief look at the entanglement of causes of hearing loss (i.e. noise exposure, health and perhaps age), noise exposure inside and outside the workplace, aural health and industrial law. The article points to some of the difficulties without attempting to resolve them.
Noise Exposure of Music Teachers: Links to further information
This doubles as the References section for all the other pages. It lists journal articles, theses, acoustics texts and more, with hyperlinks to those which are available online.
The OHS literature calls all sound ‘noise’ and I have done the same in these pages. It may seem absurd for a musician to do so but it seemed important to do it here, as a means of stressing that all sound has the same physical effects on our ears whatever it does to our brains, emotions or, dare I say it, souls.
More trivially, ‘Occupational Health and Safety’ (OHS) is exactly synonymous with ‘Workplace Health and Safety’ (WHS); different names are used in different states and countries. To avoid confusion between similar bodies in different places, I have sometimes added country names in parentheses.
Many people have assisted in my work on this subject, and I would like to acknowledge their encouragement and/or constructive advice. Thank you all!
Any remaining errors and omissions are, of course, entirely my own. I will do my best to rectify any errors I am alerted to, although I will not make the same promise for omissions: the subject has no clear-cut borders and I have intention of extending my work into all varieties of music teaching and/or all causes of hearing loss. However, I welcome readers’ input and will happily add resources and links to the site.
Malcolm Tattersall played piano and recorder as a child before joining the local brass band on cornet and working his way down to euphonium. He studied sciences (maths/physics) at school and went on to a cadetship in communications engineering which included studies at Royal Melbourne Institute of Technology. On deciding that music was more fun, he supported himself as a computer programmer for a year while catching up on music studies, then enrolled in music at Melbourne University.
He began teaching woodwinds in Victoria in the late 1970s. Since then he has taught recorder, flute, clarinet, saxophone and tin whistle in primary and secondary schools (both state and non-state), TAFE, studio, summer school and adult education settings in Victoria and Queensland, and played in, and/or conducted, ensembles employing all of these instruments and more. For more information about his activities as composer and writer, please visit the main section of his Home page.
