Welcome to the PF.Piotr99 said:Please can someone explain me how high levels of ultrasound can be created in Air?
Should we consider the Ultrasound or we should concentrate only on sound level in Air as frequency ultrasound have no effect on sound level?
You do understand that high levels of ultrasound in air can be dangerous, right? Can you say why that is true?Piotr99 said:Hi Mentor,
Thank you for reply. This is a question which is going on top of my head as I am approaching Acoustics and Ultrasound subject.
With a tone generator, an amplifier, and an ultrasonic capable speaker?Piotr99 said:...
But my theoretical questions is how high levels of ultrasound can be created in Air?
wiki claims that that is a "dubious" claim. [ref] Do you have a reference for that? I searched for about 20 minutes and couldn't find a source for the claim.I know based on Sound Level in Air that the highest level is around 194 dB. But can we say it will be 194 dB for ultrasound as well?
I don't know. Have you googled it?Have high frequency affect the sound level due to strong attenuation of Ultrasound in air?
Well, I don't know about Piotr, but I now understand.berkeman said:You do understand that high levels of ultrasound in air can be dangerous, right? Can you say why that is true?
It can be dangerous, both for people and for things， be careful， if you're not a professional or a scientistberkeman said:You do understand that high levels of ultrasound in air can be dangerous, right? Can you say why that is true?
High levels of ultrasound in air are created through the use of specialized equipment, such as ultrasound transducers, which emit high frequency sound waves. These sound waves are then amplified and focused to create high levels of ultrasound.
The frequency range of ultrasound in air typically falls between 20 kHz and 100 kHz, though it can vary depending on the equipment used and the specific application.
In general, high levels of ultrasound in air are not considered harmful to humans. However, prolonged exposure to very high levels of ultrasound can potentially cause discomfort or damage to the ears and other sensitive tissues.
The intensity of ultrasound in air is typically measured in terms of decibels (dB). This measurement takes into account both the frequency and amplitude of the sound waves being emitted.
High levels of ultrasound in air have a wide range of applications, including medical imaging, industrial cleaning, and non-destructive testing. They can also be used for communication and navigation in certain underwater environments.
