Highest achievable compression frequency

Click For Summary

Discussion Overview

The discussion revolves around the upper limits of frequency achievable with audio signal generators, specifically in the context of compression waves. Participants are interested in practical realizations of high-frequency sound generation, particularly in the range of tens to hundreds of gigahertz, and the potential use of piezoelectric materials or other technologies.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the highest frequency achievable for compression waves using audio signal generators, expressing interest in practical applications rather than theoretical limits.
  • Another participant suggests that piezoelectric materials have a high potential frequency response, but also proposes that a thin ferromagnetic membrane might be a better option.
  • A further inquiry is made regarding specific frequencies that could be achieved, indicating a preference for information on what is currently possible or anticipated rather than the methods of achieving it.
  • One participant expresses uncertainty about the topic and suggests rephrasing the question for clarity or seeking expertise in a different forum section.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific frequencies achievable, and multiple views on potential technologies and methods remain. The discussion is unresolved regarding the practical limits of frequency generation.

Contextual Notes

Limitations include the lack of specific frequency data and the dependence on the definitions of materials and technologies discussed. The discussion does not resolve the feasibility of achieving the proposed frequency ranges.

I am wondering what the upper limit for frequency is currently as far as audio signal generators go.

Basically I want to know how high of a frequency I can get on a compression wave. I don't mean the theoretical limit based on the atomic spacing in the medium, but rather if I want to buy a signal generator (speaker) how high I will be able to get. Ultimately I am interested in creating a standing wave with very small widths for the compression region. I am thinking in the 10's to 100's of GHz but I don't know if such frequencies are realizable. I am suspecting that if it is going to be possible that piezoelectrics are going to be required.

Can someone help me out? Thanks.

Piezo materiels do have a very high potential frequency response. Even still, a thin ferromagnetic membrane could be better.
 
do you have any idea of what frequencies could be achieved though? I am less interested in how it is done, just what can be done, or is anticipated being able to be done.
 
Yeah, I don't know jeberd. Maybe some expert will jump in. If not, maybe you could re-phrase the question and post it in the General Physics section. I've had luck there.
