I found this interesting bit of research at the PsyBlog, run by Jeremy Dean, a Psychology researcher at the University College London. The post is entitled Why Loud Music in Bars Increases Alcohol Consumption, and concerns some recent research conducted into the relationship between volume and drinking patterns. Specifically, Dean cites two studies, one in Glasgow, Scotland and the other in France. In some ways the findings are obvious, but it does tend to confirm what you probably already guessed. The PsyBlog starts with the premise that the average bar traditionally keeps the lights dim and the music loud.
But turning the music up so loud that people are forced to shout at each other doesn’t have quite the same beneficial effect on social interactions. Because everyone is shouting, the bar becomes even noisier and soon people start to give up trying to communicate and focus on their drinking, meaning more trips to the bar, and more regrets in the morning.
Of course this is exactly what bar owners are hoping for. People sitting around quietly nursing their drinks for hours are no good for profits. Talkers aren’t the best drinkers. At least that is the received wisdom in the industry.
The first study, Sound Level of Environmental Music and Drinking Behavior: A Field Experiment With Beer Drinkers, was published in the journal Alcoholism: Clinical and Experimental Research. Their results indicated “that high level volume led to increase alcohol consumption and reduced the average amount of time spent by the patrons to drink their glass.”
The second study was published in the journal Popular Music & Society, and was titled Alco-pop? The Use of Popular Music in Glasgow Pubs.
Here’s a bit more as to how the research was conducted.
The level of the music was randomly manipulated to create the conditions of a true experiment. It was either at its usual volume of 72dB or turned up to 88dB. For comparison: 72db is like the sound of traffic on a busy street while 88db is like standing next to a lawnmower.
Sure enough when the music went up the beers went down, faster. On average bar-goers took 14.5 minutes to finish a 250ml (8 oz) glass of draught beer when the music was at its normal level. But this came down to just 11.5 minutes when the music was turned up. As a result, on average, during their time in the bar each participant ordered one more drink in the loud music condition than in the normal music condition.
The observers even measured the number of gulps taken to finish each drink — the level of the music was found to have no effect on this. So the faster drinking was as a result of more gulps rather than bigger gulps.
The conclusions from both studies seem to validate one another, suggesting a universal application. The results do seem to favor a causal connection between louder music and increased drinking, but what they don’t answer is why this is the case. As Dean puts it. “Some think that people drink instead of talking while others have argued that they drink more because the music creates greater levels of arousal, which then leads to more drinking.”
Personally, I prefer a bar where I can hear myself think, where pleasant conversation is encouraged, but then I prefer to sip, not gulp, my beer in almost any environment. So clearly, I’m not the target demographic, nor I suspect are most hardcore beer geeks, but it still is a fascinating peek into what makes us tick — and drink.
UPDATE: The BC Brews Blog also came across this study independently and posted about it in Loud Music = Heavier, Faster Drinking.
