Frequency vs response Curve of a microphone

[sanado]

Hi, was just hoping that you could clear up a mis-understanding i have:

In a frequency response curve, the y-axis is a decibel scale. Is this a comparison of the microphones response to the reference sound in relation to sound intensity.
eg. If the microphone has a +5 db for a particular sound, does this mean that it is 5b louder than the input sound that was put into the microphone?

Yes I believe so. That represents an amplification. Though in general the value of the frequency response lies in the relative output across your spectrum of interest, to identify non-linearity.

Hello,

Thank you for your question. The frequency response curve of a microphone is a graphical representation of how the microphone responds to different frequencies of sound. The y-axis represents the output level in decibels (dB) and the x-axis represents the frequency of the sound in hertz (Hz).

The decibel scale on the y-axis is a logarithmic scale that measures the ratio of the output level of the microphone to the input level. This means that a +5 dB response at a certain frequency does not necessarily mean that the microphone is 5 dB louder than the input sound. It simply indicates that the microphone is outputting at a level 5 dB higher than the input level at that specific frequency.

In other words, the frequency response curve does not directly measure the loudness of the microphone, but rather the difference in output level compared to the input level at different frequencies. It is important to note that the reference sound used for comparison can vary and may affect the results of the frequency response curve.

I hope this helps to clear up any misunderstandings. Let me know if you have any further questions.
