I am sitting at my kitchen table eating chocolate in the name of science. (Turns out I am pretty good at science). I am trying out some “sonic seasoning” whereby if I listen to a low-pitched sound, my taste awareness somehow shrinks to the back of my tongue and focuses on the chocolate’s bitter elements. When I switch to a high frequency, the floodgates to sweetness open up and my entire mouth kicks back in a warm, sugary bath. It is a curious sensation because it does not feel, to me at least, as if the chocolate tastes different.
It is more that the sounds are twisting my gray matter, changing how it perceives the taste.
The sound is what sensory science nuts call modulating taste, and the past few years have seen a boom in research in this area.
Sound is the final frontier in food presentation. Restaurants agonize over menus, crockery, furniture and lighting, yet often any old CD will be stuck on background music with nary a thought. However, now that we are starting to understand that everyone has synaesthetic tendencies when it comes to taste, sound is set to play a bigger part in our eating experience.
Ben & Jerry’s, for example, is considering a sonic range of ice-cream flavors, with QR codes on the tubs that will allow eaters to access complementary sounds via their phones.
Back in 1997, British chef Heston Blumenthal introduced his iPod-enhanced seafood dish, Sounds of the Sea, but that was a more literal, more Pavlovian association: eat fish, listen to the sea, fish tastes fresher and better.
However, a number of recent experiments have shown how abstract sounds can turn tastes up or down by remote control, as it were.
The Crossmodal Laboratory at Oxford University fed a group of volunteers some cinder toffee while playing them high and low-frequency sounds, and asked them to rate the taste on a scale running from sweet to bitter.
Just as I experienced in my kitchen, high notes enhanced sweetness and low brought out the bitter. However, a laboratory setting is far removed from real life, so Charles Spence, who runs the lab, collaborated with food artist Caroline Hobkinson to test whether the results would be replicated out in the field.
For one month, London restaurant House of Wolf served a “sonic cake pop” of chocolate-coated bittersweet toffee, which came, intriguingly, with a telephone number.
On the other end of the line was an operator instructing the diner to dial one for sweet and two for bitter, and they were played the high and low-pitched sounds accordingly.
Hobkinson said: “It makes me laugh because it works every time, and people say, ‘Oh! That’s so weird!’”
She put on a similar event at the Royal Institute in London for which, instead of playing the synthesized sound clips, the Royal Academy of Music devised some abstract live performances that would do the trick with more feeling.
“It works with coffee, too,” she added, and she foresees exciting possibilities such as sound replacing sugar in your morning espresso.
Meanwhile, another study by Spence also matched the savory taste, umami, with low pitches.
Confirming the hunches of so many ravenous airplane passengers, a study published in 2011 found that loud background noise suppresses saltiness, sweetness and overall enjoyment of food. (For flyers, this is compounded by the high altitude blocking nasal passages, and therefore access to aromas.)
Incidentally, for those among you who curse that you cannot hear yourself think, or indeed taste, in some restaurants, it is not unheard of for the background din to register 90 decibels, which is a tad louder than commercial flights.
“Have you ever noticed how many people ask for a bloody mary or tomato juice from the drinks trolley on aeroplanes? The air stewards have, and when you ask the people who order, they tell you that they rarely order such a drink at any other time,” Spence said.
Spence reckons this is because umami may be immune to noise suppression. If he proves his hypothesis, perhaps concentrating on umami-rich ingredients such as tomatoes, parmesan, mushrooms and cured meats in the sky could help obliterate plane-food hell.
Last year, a paper published in the journal Chemosensory Perception looked at matching pitches and instruments with odors (smell being the dominant sense in flavor appreciation).
The aromas of candied peel, dried plums and iris flowers were all matched with piano significantly more than woodwind, strings or brass.
Musk, on the other hand, was overwhelmingly brass. In terms of pitch, candied orange and irises were significantly higher than musk and roasted coffee.
This is just the start of a long and winding road of research, and the findings will undoubtedly be noted most by multinational companies keen to manipulate us into loving their products.
Have you knowingly experienced synaesthesia when it comes to taste? Does matching sound to taste seem a massive, unnecessary faff? Does restaurant noise often spoil your meal?
Two sets of economic data released last week by the Directorate-General of Budget, Accounting and Statistics (DGBAS) have drawn mixed reactions from the public: One on the nation’s economic performance in the first quarter of the year and the other on Taiwan’s household wealth distribution in 2021. GDP growth for the first quarter was faster than expected, at 6.51 percent year-on-year, an acceleration from the previous quarter’s 4.93 percent and higher than the agency’s February estimate of 5.92 percent. It was also the highest growth since the second quarter of 2021, when the economy expanded 8.07 percent, DGBAS data showed. The growth
In the intricate ballet of geopolitics, names signify more than mere identification: They embody history, culture and sovereignty. The recent decision by China to refer to Arunachal Pradesh as “Tsang Nan” or South Tibet, and to rename Tibet as “Xizang,” is a strategic move that extends beyond cartography into the realm of diplomatic signaling. This op-ed explores the implications of these actions and India’s potential response. Names are potent symbols in international relations, encapsulating the essence of a nation’s stance on territorial disputes. China’s choice to rename regions within Indian territory is not merely a linguistic exercise, but a symbolic assertion
More than seven months into the armed conflict in Gaza, the International Court of Justice ordered Israel to take “immediate and effective measures” to protect Palestinians in Gaza from the risk of genocide following a case brought by South Africa regarding Israel’s breaches of the 1948 Genocide Convention. The international community, including Amnesty International, called for an immediate ceasefire by all parties to prevent further loss of civilian lives and to ensure access to life-saving aid. Several protests have been organized around the world, including at the University of California Los Angeles (UCLA) and many other universities in the US.
Every day since Oct. 7 last year, the world has watched an unprecedented wave of violence rain down on Israel and the occupied Palestinian Territories — more than 200 days of constant suffering and death in Gaza with just a seven-day pause. Many of us in the American expatriate community in Taiwan have been watching this tragedy unfold in horror. We know we are implicated with every US-made “dumb” bomb dropped on a civilian target and by the diplomatic cover our government gives to the Israeli government, which has only gotten more extreme with such impunity. Meantime, multicultural coalitions of US
