Is there anything that focuses sound like is done with a lazer? That is where you wouldn't be able to hear anything unless you were in the beam path and maybe the intensity would be magnified.

I like Serena said:Interesting topic!
Makes me wonder if you can *zap* stuff over long distances with your uaser.

Studiot said:I understood that lazing action was about coherence, not focus?
berkeman said:a stimulated emission analog mechanism at ultrasonic frequencie.
Wouldn't a simple microphone+amplifier+speaker provide the sound analog of light amplification by stimulated emission? The speaker emits amplified sound in phase with the sound that hits the microphone.berkeman said:Yeah, the SE in LASER is the stimulated emission part, which is what I found surprising about the UASER article. They seem to be implying that they have been able to come up with a stimulated emission analog mechanism at ultrasonic frequencies. I haven't read the UASER article in a lot of detail yet, though, so I can't say much about their claim.
That's pretty neat -- terahertz (ultra)sound!cpt_carrot said:Also don't forget the http://news.cnet.com/8301-17912_3-10267528-72.html" which creates a coherent beam of phonons
A sound laser is a device that uses focused sound waves to create a highly concentrated beam of sound. It works similarly to a traditional laser, but instead of using light waves, it uses sound waves to create a beam of sound.
A sound laser works by using a series of transducers to convert electrical signals into sound waves. These sound waves are then focused and amplified through a series of mirrors and lenses to create a concentrated beam of sound that can travel long distances.
Sound lasers have a wide range of applications, including in medical procedures, industrial processes, and entertainment. They can be used for precise cutting and welding, non-invasive surgery, and even for creating immersive sound experiences in concerts and theme parks.
Yes, sound laser technology is generally considered safe. Unlike traditional lasers, which use potentially harmful light waves, sound lasers use non-ionizing sound waves that are not harmful to human tissue. However, caution should still be taken when using sound lasers, as they can produce high-intensity sound that can damage hearing if not properly controlled.
Yes, sound lasers are also known as acoustic lasers or sonic lasers. These terms are often used interchangeably to describe the same technology of using focused sound waves to create a beam of sound.
