Discussion Overview

The discussion revolves around the feasibility of receiving and emitting sound waves specifically at a frequency of 1100 Hz. Participants explore various devices and methods for detecting and displaying this frequency, as well as the characteristics of sound wave reception.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about devices that can receive sound waves at 1100 Hz, expressing uncertainty about the availability of such technology.
  • Another participant clarifies that many objects can receive sound waves, but not all can process them meaningfully, prompting questions about the specific requirements for detection.
  • A follow-up post seeks clarification on whether the desired device should detect only the 1100 Hz frequency or a range above it, indicating a need for specificity in the request.
  • It is suggested that a tuning fork could respond to a narrow band of frequencies, and that a microphone combined with software or an analog filter could isolate the desired frequency.
  • Another participant mentions that handheld acoustic analyzers can detect a range of frequencies and provide customizable displays for the user’s needs.
  • A technical contribution includes a description of a simple circuit using an op-amp that can amplify signals at 1100 Hz and trigger an LED when a certain sound level is reached.

Areas of Agreement / Disagreement

Participants express various ideas about the devices and methods for detecting 1100 Hz sound waves, but there is no consensus on a single solution or approach. Multiple competing views and suggestions remain in the discussion.

Contextual Notes

Some participants note the need for clarity regarding whether the device should detect only the specified frequency or a broader range, indicating potential limitations in the initial inquiry.

Who May Find This Useful

This discussion may be of interest to individuals exploring sound wave technology, acoustic analysis, or those seeking to understand frequency detection methods.

Hopefully i am not wasting anyones time, as i don't know a lot about sound waves etc.. but i was wondering if anyone could help. Is there such a thing that receives sound waves of around 1100hz. maybe a sound receiver and emmitter? I have tried finding as much infomation online, but there is limited results. I know this may not be the 'normal type of question' but any info would help massively.

Your ear, a microphone, a brick wall?
Every object receives sound waves that reach it - not all of them do anything except absorb them.
Do you want to detect 1100hz sound, detect only this frequency, block only this frequency or what?
 
Sorry, there was no clarity in what I was asking! But yer basically Is there a device that only picks up this frequency/only picks up this frequency and above! And displays in whichever means possible(a gragh, by a light bulb, etc...) if this frequency is heard!
 
A tuning fork would respond to only one frequency (or at least a narrow band of frequencies )
The easiest way is a microphone and either a computer and some software to pull out just that one frequency, or you can do it with an analog electronics filter.
This is what the graphic equiliser on a hifi does.
 
Many hand held acoustic analyzers will do what you are looking for as well. They will pick up all frequencies up to a certain limit and will have customizable displays that you can tailor to whatever you are looking for.
 
Hello Callumbrad-
Here in thumbnail is a simple 1-opamp tuned narrowband amplifier that can be used with a microphone [STRIKE]or loudspeaker[/STRIKE] input. Voltage source V2 in circuit is a 1-millivolt signal that is swept from 500 Hz to 2000 Hz. The output signal is maximim at 1100 Hz, with an amplitude of 200 millivolts.
[added] It is straight forward to ad an op-amp that lights a LED if the sound signal level exceeds a threshold at the output of this circuit.
[added2] The LT1014 is equivalent to the LM324.
