Homework Statement
How can I measure the frequency of a really quiet sound. The software I have only measures the peak frequency (so not the frequency of the sound I want to measure which is lower f).
This doesn't really look like homework -- if it's a general interest question, I can move this thread to the EE forum.Physicist1011 said:Homework Statement

The Attempt at a Solution
A spectrum analyzer is a scientific instrument used to measure the spectrum of frequencies present in a signal. It works by taking an input signal and breaking it down into its individual frequency components, displaying them as a graph or spectrum. This allows for the identification of specific frequencies and their amplitudes within the signal.
Quiet sound frequencies, also known as low-level signals, can contain valuable information about a system or environment that may not be detectable by the human ear. By measuring these frequencies, scientists can gain a better understanding of the characteristics and behavior of a system, leading to advancements in fields such as audio engineering, telecommunications, and environmental research.
A spectrum analyzer can analyze a wide range of signals, including electrical signals, optical signals, and acoustic signals. This allows for a diverse range of applications, from analyzing audio signals in music production to measuring radio frequency signals in wireless communication systems.
A spectrum analyzer measures quiet sound frequency by taking an input signal and converting it into an electrical signal, which is then amplified and passed through a series of filters to isolate different frequency bands. The resulting signal is then displayed on a graph or spectrum, with the amplitude of each frequency represented by a peak or spike on the graph.
Spectrum analyzers are commonly used in scientific research to study the properties of sound, light, and other electromagnetic waves. They are also used in fields such as acoustics, telecommunications, and signal processing to analyze and troubleshoot signals. In addition, spectrum analyzers are frequently used in environmental research to monitor noise pollution and study the effects of sound on wildlife and ecosystems.
