Is stomping a friction sound, and is stomping an onomatopoeia?

Stomping should not be an onomatopoeia.

Here it should be action.

So there shouldn't be a sound here.

The ITTF's latest rules do not stipulate that you cannot stomp your feet. Therefore, stomping is not a foul, including many of the world's top masters who stomp their feet, just watch other people's games.

For the rules of the serve: only the end line is unexpected, above the table, vertical throw height greater than 16 cm, and unobstructed.

The latest rule is that you can't stomp your feet on the serve because it will interfere with the opponent. However, many athletes will have a slight stomping movement, as long as the sound is not loud enough to disturb the opponent, and the referee will not give a penalty. There are no requirements in the competition.

When serving, it is not allowed to stomp the foot, which will interfere with the opponent's judgment of receiving the serve.

During the competition, it is possible to stomp your feet.

There are no rules for this, and it is purely a personal hobby of athletes. There is also a plastic field, which will also produce some harsh sounds due to friction with sneakers, which is also not regulated.

The main stomping occurs when the player serves.

There's no rule, it's a matter of the individual, and everybody's stance and strength are different, and everybody's range of running on the table is completely different.

People tend to be like this, and most of them are delusions.

I can't stand the sound of metal grinding.

Afraid of heights, right?? I'm the same kind of wooden floor, and I don't dare to walk with a lot of strength.

The floor may have been freshly cleaned or waxed. Because the sole of your shoe is foam or rubber, the friction of the smooth ground is reduced, and it is easy to slide and produce sound.

All kinds of sounds in the air are caused by the vibration of objects. The frequency is related to the object that emits the sound.

Sneakers are a kind of soft rubber products, and the smooth floor produces an attraction, artificially stomping on it, will make an instantaneous greater impact between them, the sound is connected to form an uninterrupted friction sound, so the heel feeling is very loud.

Vibration makes a sound It's a principle of physics, it's as simple as that.

Even if you gently stomp on the ground in soft-soled shoes, the ground will vibrate, and if there is vibration, there will be a sound. Gently stomp on the ground with your feet, if you can't hear the sound, it's not that there is no vibration and no sound, but the vibration is slight, and the sound produced is also very slight, our hearing is limited, we can't hear it, if you measure it with an instrument, you can measure the vibration and sound.

Rubber shoes walking on the tile floor, because the friction will produce a squeaky sound, this phenomenon is very common, such as indoor ball games, athletes wear shoes often have this sound, the cleaner the floor is wiped the easier it is to have.

The sound is generated by vibration, and when you stomp your feet in sneakers, the sound is inevitable, which is related to the material and shape of your sole.

The rubber sole is elastic and is produced by friction against the surface of the tile. A small sound.

This is done at a hospital designated by the disability administration.

So this situation needs to be adjusted. Try to calm your mind as much as possible, and you won't get tangled.

People can't feel infrasound in the first place. Stomping produces infrasound waves either.

Sound waves with a frequency of less than 20 Hz (hertz) are called infrasound, which can interfere with the normal function of the human nervous system and endanger human health. Ordinary people can't feel it, they can only say that you are very good.
