Ultrasonic cleaning machine is a widely used cleaning equipment in industrial and laboratory environments, which uses ultrasonic vibration to clean various objects, such as parts, utensils, and samples. However, when we start the ultrasonic cleaning machine, we usually hear some noise. This article will explore why ultrasonic cleaning machines emit noise after startup and the possible reasons for these noises.

超聲波（bō）清洗機的核心部件之一是超（chāo）聲波換能器，它產生高頻（pín）超聲波振動。當振蕩器工作時，它會產生機械振動，這些振動會傳播到液體中，從而產生超聲波波動。這些振（zhèn）動會導致清洗（xǐ）機產生噪音，通常是一種高頻的嗡嗡聲。

One of the core components of an ultrasonic cleaning machine is an ultrasonic transducer, which generates high-frequency ultrasonic vibration. When the oscillator operates, it generates mechanical vibrations that propagate into the liquid, resulting in ultrasonic waves. These vibrations can cause noise in the cleaning machine, usually a high-frequency buzzing sound.

清洗過程中，液體中可能會產生氣泡。這些氣泡在液體中移（yí）動時會與物（wù）體表麵發（fā）生碰撞，產生小的爆破聲。這（zhè）些聲音可能會增加整體的噪音水平。

During the cleaning process, bubbles may be generated in the liquid. When these bubbles move in the liquid, they collide with the surface of the object, producing a small explosion sound. These sounds may increase the overall noise level.

清洗液體的性質也會（huì）影響清洗機的噪音水平。不同的清洗液體具（jù）有不（bú）同的粘度和（hé）密度，這會影響超聲波傳播和聲音（yīn）的產生。一些清洗液體可（kě）能（néng）會產生更多（duō）的噪音，而另一（yī）些則會減（jiǎn）少噪（zào）音水平。

The nature of the cleaning fluid can also affect the noise level of the cleaning machine. Different cleaning liquids have different viscosities and densities, which can affect the propagation of ultrasound and the generation of sound. Some cleaning liquids may produce more noise, while others may reduce noise levels.

超聲波清洗機（jī）的設計和質量也會影響（xiǎng）噪音水平。高質（zhì）量（liàng）的清洗機通常采用隔音材料和（hé）減振技術，以減少噪音（yīn）的傳播。因此，選擇合適的（de）清洗機和進行適當的維護也可以（yǐ）降低噪音問（wèn）題。

The design and quality of ultrasonic cleaning machines can also affect noise levels. High quality cleaning machines typically use soundproofing materials and vibration reduction technology to reduce the spread of noise. Therefore, selecting a suitable cleaning machine and performing appropriate maintenance can also reduce noise issues.

超聲波清洗機在啟動後會產生一定的噪音，這是由於超聲波換能器、氣泡、物體之間（jiān）的摩擦以及清（qīng）洗液體的（de）性質等多種因素相互作用所致。雖然這（zhè）些噪（zào）音（yīn）可能有些許不便，但它們通常是正常的，不會影響清洗效果。

After starting, an ultrasonic cleaning machine will produce a certain amount of noise, which is caused by the interaction of various factors such as ultrasonic transducers, bubbles, friction between objects, and the properties of the cleaning liquid. Although these noises may be a bit inconvenient, they are usually normal and do not affect the cleaning effect.
