Feel like I-dosing? [Part 2]

A few months ago my Facebook friends in the US started mentioning it. Only a few weeks later it appeared in the news in Europe, generating a lot of noise in Belgium last week when I-dosing or ‘binaural beats’ were condemned as a form of narcotics.

The phenomenon of ‘binaural beats’ was first described in 1839 by Heinrich Wilhelm Dove. It is the sensation of hearing interference beats when two slightly different frequencies are played separately to each ear. The rate of the ‘perceived’ beats were claimed to modulate ones brain waves. However, little or no evidence has been brought forward since then. The few studies that seriously studied the effect could not support this claim (e.g., Owens et al., 1998), except that that it might have some effect on attention and arousal. Quite understandable, if you listen to one of the examples (see link).

The recent media attention for this phenomenon seems to be successfully bootstrapped by a new company selling mp3’s with titles like ‘Quick Hit Simulations’ describing their product with statements like ‘binaural beats will synchronize your brainwaves and help you achieve a quick hitting simulated drug simulation.’ Prices around twenty dollar. Here is one for free :-)

Update #1: Last week The Lebanon News restarted it all over again '"Digital drugs," otherwise known as binaural beats, have sparked an outcry in Lebanon, with the Justice Minister Ashraf Rifi calling Thursday for legal measures to be taken against the product.'

Update #2: Last weekend the Dutch newspaper NRC Handelsblad referred to the Autonomous Sensory Meridian Reponse (ASMR), a label that has been pushed (and several times – quite rightly so – rejected by Wiki) by a curious group of people. A similar hoax/hype as compared to 'binaural beats'.

Hi! I tried clicking on the provided links for both the binaural example and the free binaural beat; however, the linking website is coming up with a 404 error. Thanks!
