Frequency Patterns when Moving Microphone from 0-90 Degrees

In summary, when playing a range of frequencies (100hz-10khz) through a speaker and moving a microphone from 0 degrees in front of the speaker to 90 degrees perpendicular to the speaker cone, patterns can be measured with an oscilloscope. As the angle increases, the high frequencies are expected to become less detectable due to less diffraction. The distance from the speaker cone remains the same.

in playing a range of frequencies through a speaker 100hz- 10khz what patterns would be found as a microphone is moved from 0degrees in front of the speaker to 90degree perpendicular to the speaker cone that cna be measured with an oscilloscope? i'd expect the high frequencies will become less detectable as the angle increases due to less defraction? the distance from the speaker cone remains the same.

Thread moved to Homework Help forums. Welcome to the PF, asiaduuude. Can you tell us more about what you think should be expected. What would you expect the amplitude variations to be?

1. What is the significance of moving a microphone from 0 to 90 degrees?

Moving a microphone from 0 to 90 degrees changes the directionality of the microphone, allowing it to capture sound from different angles. This can affect the frequency response and sound quality of the recorded audio.

2. How does the frequency response change when moving a microphone from 0 to 90 degrees?

The frequency response of a microphone can change when it is moved from 0 to 90 degrees due to the varying angles at which sound waves enter the microphone. This can result in differences in the intensity and clarity of certain frequencies.

3. What is the polar pattern of a microphone and how does it relate to frequency patterns?

The polar pattern of a microphone refers to its directional sensitivity and its ability to pick up sound from different angles. The frequency patterns can be affected by the polar pattern as the directionality of the microphone can impact the frequencies that are captured.

4. Can the frequency patterns be controlled by adjusting the microphone angle?

Yes, the frequency patterns can be controlled to some extent by adjusting the microphone angle. However, the specific changes in frequency response will also depend on the polar pattern and other factors such as room acoustics and distance from the sound source.

5. How can the knowledge of frequency patterns when moving a microphone be used in recording or live sound settings?

Understanding frequency patterns when moving a microphone can be useful in recording and live sound settings as it can help in selecting the best microphone for a specific purpose and placement. It can also aid in achieving a desired frequency response and capturing a balanced mix of sound from different sources.
