A company I used to work for many years ago had a highly distinctive, memorable jingle that it used in all of its TV ads. I was doing full time IVR design at the time, and I realized that this jingle could be used as an earcon, a branded auditory icon for the company's many IVRs. I wrote up a proposal on auditory branding and gave a big pitch to one of the execs, explaining that with all the attention and money being spent on visual branding at the company, it would make sense to spend a little time thinking about auditory branding. I offered to lead the effort. The exec listened politely and nodded several times, but nothing ever came of it.
So, I was interested in this article about auditory ads and attention. Despite the breathless title, there is probably nothing in the actual research related to addiction. Rather, there are definite neurological correlates to memory and attention, which is probably what was being measured here. In fact, the research was conducted by a company that is selling its services, rather than by a science lab, so I have questions about the validity of the findings.
In any case, my ex-company's memorable ad jingle appears in the "Top 10" list. When you own a inimitable resource like this it pays to figure out a way to leverage it. There is certainly an idea here that should be followed up on.
