If you are in a hurry and want to find out the Best microphone with a flat frequency response, then I highly recommend the Heil sound PR 35 Dynamic Microphone
If you are searching for a microphone with a flat frequency response then you should definitely read this article.
There are a couple of reasons why you may need to purchase a microphone that has not been altered.
For example, you may be a phonetician looking for a microphone to record audio in your field or you are probably just someone that wants to record and hear audio in it’s true form.
Whatever the case may be, picking a flat microphone should not be confusing to you.
While there are certain considerations you need to look out for, after reading this article you will know them all.
In this article, we will be looking at the top 5 flat frequency response microphones, things to consider before you make a purchase, what it means for a microphone to have flat frequency response and how to ensure you get the best from your new microphone.
At a glance, these are the top 3 Microphones with flat frequency response

What is a microphone’s frequency response?
A microphone’s frequency response is simply a measurement of how a particular microphone responds to a range of frequencies.
What this means is that different microphones respond in a particular way to different frequency ranges.
So when looking for one that has a flat frequency response, the main thing is to ensure that the mic behaves in a particular way within a specified range.
Most microphones fall into a particular frequency response range. This is because the human ear can hear and produce sounds within this range; 20 to 20,000 Hz.
If you are looking for a mic with a flat frequency response range, then you should get one that falls within the 150Hz to 250Hz range.
At this range, what goes into the microphone is what you tend to hear coming out.
There are no alterations or distortions trying to make the audio sound “better”
Here is a frequency response chart showing you the flat range of a popular microphone.

Things to consider before you make a purchase
1. What is the frequency response range
Obviously while looking for a flat microphone, you want something that falls within 150Hz to 250 Hz range.
This is because most mics tend to enhance certain frequencies to make the voice sound much better.
But if you are interested in listening to what really happens acoustically, rather than a recording that sounds good then you should get this right.
So make sure that you do your research and you get the right mic that falls within this required range.
2. How durable is it?
Another factor you want to consider is the durability and to some extent the portability of the mic.
To get a good mic that will last for a long time, you should be prepared to shell out some cash
This could well run into hundreds of dollars. As a result, you want something that is durable and does not break easily.
One way to ensure this does not happen is to make sure that the microphone is built with metal casings.
Also you want to get something that is portable and can be easily moved about.
This will depend largely on your reason for buying a mic. If it is your main microphone or it is to be used as a backup then you want something that you can easily pack up and transport.

Frequently Asked Questions
1. What does it mean to have a flat frequency?
Simply put having a flat frequency means that the audio quality coming out of the microphone is the same quality as that which entered without any enhancements in any particular phase.
This is very important for vocalists and phoneticians that like listening to audio in its “true and pure form”.
For an instrument to be said to have a flat frequency response it must fall within this range; 20Hz to 20KHz.
2. What is the sensitivity of a microphone?
The sensitivity of a microphone is simply the easy at which the microphone picks up external sounds.
Some microphones are very sensitive meaning that they pick up the required sounds and some more making mixing of the track a bit difficult.
It is usually measured with a 1KHz sine wave at a 94 dB sound pressure level.
3. What is the frequency response curve?
This is a diagrammatic representation of the signal amplitude or gain plotted against frequency.
This helps easily give a representation of where the instrument has been enhanced to make it sound better.
4. How can I change my mic sensitivity?
Changing your mic sensitivity has a lot of advantages especially when being used in a noisy environment.
The easiest and simplest way to get this done is to do so in your recording DAW or your operating system.
Here is a step by step guide showing you how to reduce the sensitivity of your microphone.
5. What is a high frequency response?
When an instrument is said to have a high frequency, it means that it’s frequency range has been altered to improve the audio quality.
This is usually done to home use speakers and headphones to make them sound better
