Can you tell the cold water from the hot water by what it sounds like?

Why does water taste strange to us if we have left it out all night?

It sounds strange (and does not go with seconds), but apparently it is possible to hear the difference in sound between hot and cold water.

Condiment Junkie is an advertiser focused on working on the senses, with several projects focused on exploring sight, taste, smell, touch and hearing; specifically, they have created several advertisements related to sound and how we associate certain sounds with certain sensations.

When you work based on sound, there are many things to consider, especially if you want to present a product in a more attractive way. Will you get more sales if you record the sound of a cup of hot tea or cold tea?

Hear the difference in sound between hot and cold water

In fact, the question goes further: Is there really a difference between listening to hot water and cold water? Or at least, is there so much difference to bother heating or cooling a drink before recording?

Of course, this is the type of question that can be easily solved with an experiment, in which they recorded cold water and hot water being served in a glass, They uploaded the sound files to Soundcloud, and asked the Internet.

Now you have the opportunity to see for yourself. Note that is the same amount of water, and it is being poured into the same glass, so you should not take into account considerations such as shape.

Glass 1 Hot or cold water?

Glass 2 Hot or cold water?

Next we are going to solve the riddle, so if you haven’t answered yet, you have time to do so.



Already? Well, as you have heard, the sound of both types of water is very different, much more than we could imagine.

The answer is that the first glass was cold water, and the second glass was hot water. You’re right? 96% of the people who answered in the original campaign were right.

Why does the water sound different depending on the temperature? Because temperature affects the viscosity of liquids; The more we heat a liquid, the less viscous it will be and therefore suffer less resistance to flow. In the same way, when we heat a liquid it loses density.

The difference in sound is due to the amount and strength of the splash when the water enters the interior of the glass; In the case of hot water, the resulting sound contains more high frequencies due to the bubbles that appear when the water is poured.

Have you got it right?
