Health warning: reading newspapers can be dangerous
Oh dear.
This article appeared in the Christmas edition of the BMJ, along with other seasonal fayre, such as the usage of Coca-Cola vaginal douches for birth control, and a systematic review of the efficacy of Frankincense.
I'm afraid that it's not a "provocative (albeit suspiciously anecdotal) study". It runs to 1.5 pages, and describes the findings of tinnitus in one patient, which it appeared may have been linked to his golfing. The term "sonic boom" appears once, and is a quote from another golfer, found on the internet. Oddly, the rags decided to use the term "sonic boom" rather than "unusual clanking sound", another quote from the Internet. The authors then got a pro to hit a total of 36 shots on 12 different drivers, and measured the sound produced. They conclude by saying "The study presents anecdotal evidence that caution should be exercised by golfers who play regularly with thin faced titanium drivers to avoid damage to their hearing". End of story.
Except, of course, that it seems to have been reported by various newspapers, including the Daily Mail. "NHS Choices" (what on earth is that?!) also reads the Daily Mail, and saw fit to comment on the Mail's story. The comment is as long as the article and is, to be frank, bollox. It talks about "low level evidence", and says "There was no statistical comparison between the noise generated when using steel drivers compared to titanium ones". There were *3* measurements for each of the 12 drivers, with all 3 shown by pretty pictures of golf balls on a graph - what sort of statistical analysis, exactly, is NHS Choices suggesting should have been carried out?
The real story here is that you shouldn't believe what you read in the papers, and someone at NHS Choices is spending taxpayer's money to write 1014 words where 20 would have done the job better. What a surprise.
