In summary, the conversation discussed finding the distances L1 and L2 of a source of sound located on the +x axis from two microphones located at the origin and on the +y axis. The speed of sound was given as 343 m/s and the microphones were separated by a distance of 1.5 m. Using the given information, the distances were calculated to be L1=1.996 meters and L2=2.4968 meters. The conversation also highlighted the importance of including units in calculations.

Homework Statement



One microphone is located at the origin, and a second microphone is located on the +y axis. The microphones are separated by a distance of D=1.5 m. A source of sound is located on the +x axis, its distances from microphones 1 and 2 being L1 and L2, respectively. The speed of sound is 343 m/s. The sound reaches microphone 1 first, and then .00146 s later, microphone 2. Find the distances L1 and L2


Homework Equations





The Attempt at a Solution



L1= x
L2= x + (343 * .00146)

1.5^2 + X^2 = (x+ (343*.00146))^2
x= 1.996

L1=1.996
L2=2.4968

Units!

L1 = 1.996 lightyears? meters? yards? GeV-1?
 

What is the purpose of a microphone?

A microphone is a device that converts sound waves into electrical signals, allowing for amplification and recording of audio.

How does a microphone work?

A microphone contains a diaphragm that vibrates in response to sound waves. This vibration is then converted into an electrical signal through the use of a coil and magnet.

What are the different types of microphones?

There are several types of microphones, including dynamic, condenser, and ribbon microphones. Each type has its own unique features and is suited for different purposes.

What factors affect the quality of microphone sound?

The quality of microphone sound can be affected by factors such as the type of microphone, the environment in which it is used, and the distance between the microphone and the sound source.

How can I improve the sound quality of my microphone?

To improve microphone sound quality, you can adjust the microphone placement, use a pop filter to reduce unwanted noise, and make sure the microphone is compatible with your recording device.
