This microphone setup guide is for anyone in Bangladesh who records YouTube videos, podcasts, online classes or game streams at home and hears fan noise, echo or hum in the playback. If you are wondering how to reduce background noise in microphone recordings, the short answer is: move the mic closer to your mouth, lower the gain, point the back of the mic at the noise, and soften the room. Software comes last, not first, and most of these fixes cost nothing.
How to Reduce Background Noise in Microphone Recordings: The Basics
A typical flat in Dhaka, Chattogram or a district town is hard on microphones. Tiled floors and plastered walls bounce sound around. A ceiling fan runs most of the year. Horns and construction come through the windows, and an IPS, generator or fridge adds a low hum.
The goal is simple: make your voice much louder than everything else at the microphone. Every tip below either makes your voice louder at the mic or makes the noise quieter.
Step 1: Mic Placement and Distance
Distance is the most powerful setting you have. Each time you halve the distance between your mouth and the mic, your voice gets about 6 dB louder, while the fan across the room stays the same. You can then turn the gain down, and the noise drops with it.
- Dynamic mics: 5 to 10 cm from your mouth, roughly the width of your hand.
- Condenser mics: 15 to 25 cm in a quiet room.
- Angle: aim at your mouth from slightly to the side or above, so air from "p" and "b" sounds passes the capsule.
- Stay steady: leaning back by 20 cm makes your voice drop and the echo rise.
Check which part is the front. Many condenser mics are side-address, so you speak into the side. Most podcast dynamics, such as the MAONO PD200X and FIFINE K688, are end-address, so you speak into the top.
Step 2: Gain Staging Without Distortion
Gain is how much the mic signal is boosted. Too low and you raise it later along with the hiss. Too high and loud words clip, which cannot be repaired, and the fan is boosted too.
- Set the computer's input level (Windows Sound settings or your app) to around 70 to 80 percent and leave it.
- Speak at the loudest level you will really use, including laughing.
- Turn the gain knob until those moments peak around -10 to -6 dB on the meter, well below the red.
- Stay silent for ten seconds and listen on headphones. If that silence is noisy, move closer and lower the gain.
Use one gain control only. Keep "auto gain" off, because it raises the fan noise every time you pause.
Step 3: Use the Polar Pattern to Reject Noise
Most creator mics are cardioid: they hear the front best and the back least. Position the mic so its back faces the main noise, such as the window, the door or the PC. For an overhead ceiling fan, bring the mic in from above on a boom arm and angle it down toward your mouth, so the back of the mic faces the fan. If your mic has a pattern switch, keep it on cardioid for one voice.
Step 4: Dynamic vs Condenser for Noisy Rooms
A condenser mic is sensitive and detailed. In a quiet, furnished room it sounds lovely, but in a tiled room with a fan it records every sound. A dynamic mic is less sensitive and works best close up, so distant noise is much lower. For most Bangladeshi homes, a dynamic mic is the easiest way to reduce background noise in microphone recordings without treating the room.
Dynamic options we sell, at the time of writing:
- MAONO PD100U dynamic USB microphone (3,400 taka): USB-C with a gain knob, the cheapest way into a dynamic.
- MAONO PD200X USB/XLR dynamic mic (4,700 taka): USB today, XLR with a mixer later.
- FIFINE K688 USB/XLR dynamic (6,000 taka): popular for podcasts in untreated rooms.

Step 5: Pop Filter, Foam, Boom Arm and Shock Mount
Pop filter or foam windscreen
A pop filter stops the air bursts from "p" and "b". A foam cover does the same and also reduces rumble from a fan blowing onto the mic. Many mics include foam in the box, so check before buying one.
Boom arm
A desk tripod keeps the mic far away and passes every keyboard tap into the recording. A boom arm brings the mic close and lifts it off the desk. The MAONO AU-B01 boom scissor arm (1,200 taka) clamps to desks up to 4.5 cm thick. The sturdier Maono BA37 (2,900 taka) holds mics up to 2.5 kg, and the MAONO PD200X + Boom Arm Stand bundle (6,300 taka) gives you both in one box.
Shock mount
A shock mount holds the mic in elastic bands so desk and floor vibrations do not reach it. Many dynamics have internal isolation and work fine in a standard clip. If you hear thumps when you touch the desk, add one.
Step 6: Simple Room Fixes for Echoey Tiled Rooms
You do not need expensive foam panels. Soft, heavy things absorb echo better:
- Record in the bedroom. A bed and a wardrobe full of clothes are the best free treatment.
- Put a rug or thick bedsheet on the tiled floor in front of you.
- Close the curtains, or hang a thick blanket behind the mic.
- Avoid corners and empty rooms.
- Switch off the fan and AC for short takes, and record when traffic is lighter.
Step 7: USB vs XLR and Audio Interface Basics
A USB mic has its own preamp and converter: plug it into a laptop and record. It is the simplest setup for one person.
An XLR mic needs an audio interface, mixer or sound card with a preamp. Dynamic mics have a fairly low output, so the preamp must give plenty of clean gain. XLR condensers also need 48V phantom power, which dynamics do not, so leave it off unless a condenser is connected.
For streaming and podcasts, the Maonocaster AMC2 NEO mixer and sound card (4,900 taka) offers an XLR input with up to 60 dB of gain, 48V phantom power, headphone monitoring and a battery rated for up to 7 hours, handy during load-shedding. For lights and cameras, see our YouTube and podcast studio starter guide.
Step 8: Software Noise Suppression (Use It Last)
- Calls: Zoom, Google Meet and Discord have built-in noise suppression. Keep it moderate.
- Streaming: OBS Studio offers noise suppression, noise gate and high-pass filters for the mic source.
- Recordings: editors like Audacity reduce steady noise using a few seconds of silence as a noise profile.
- High-pass filter: cutting below about 80 Hz removes traffic and footstep rumble.
Use light settings. Heavy suppression makes voices sound watery or robotic. Software handles steady fan noise well, and sudden horns badly.
Microphone Troubleshooting Table
| Problem | Likely cause | Fix |
|---|---|---|
| Constant whoosh | Fan or AC, gain too high, mic too far | Move closer, lower gain, slow the fan, add foam |
| Low hum or buzz | Laptop charger, IPS nearby, ground loop, cables beside adapters | Test on battery, move cables away from power, use one power strip, try another cable or port |
| Hollow, echoey voice | Hard tiled room, speaking far away | Speak closer, add rugs, curtains and blankets |
| Distortion on loud words | Gain too high | Lower gain until peaks sit around -10 to -6 dB |
| Quiet voice with hiss | Wrong side of the mic, weak preamp | Speak into the front, get closer, use a preamp with more clean gain |
| Thumps and pops | Plosives, desk knocks | Pop filter or foam, speak slightly off-axis, use a boom arm |
| Wrong mic recorded | Laptop mic set as default | Select the USB mic as input in system settings and each app |
Microphone Setup Guide: How to Choose Your Setup
- Noisy or echoey room? A dynamic mic, 5 to 10 cm away.
- Laptop only? A USB or USB/XLR mic in USB mode.
- Two hosts or a mixer planned? USB/XLR mics plus a sound card with clean gain.
- Desk taps or pops? Add a boom arm and use the foam cover.

Frequently Asked Questions
How do I reduce background noise in my microphone for free?
Move the microphone closer to your mouth and lower the gain, so your voice is louder than the room. Point the back of the mic toward the window, door or fan. Record in a furnished bedroom, close the curtains, and switch the fan off for short takes. These steps cost nothing and usually help more than software.
Why does my microphone pick up the ceiling fan?
Fan noise reaches the mic as steady air and motor sound, and moving air hitting the capsule adds rumble. A sensitive condenser, high gain or sitting far from the mic makes it worse. Speak closer, reduce gain, fit a foam cover and lower the fan speed while recording. A dynamic mic also picks up much less of it.
What causes humming in a USB or XLR microphone?
Hum usually comes from electrical interference: a laptop charger, an IPS or inverter nearby, a ground loop between devices on different sockets, or cables running beside power adapters. Test with the laptop on battery, move cables away from power bricks, plug everything into one strip, and try another cable or USB port.
Is a dynamic microphone better than a condenser for a noisy room?
Usually yes. A dynamic mic is less sensitive and works best close to the mouth, so sounds from across the room are much quieter in the recording. A condenser captures more detail but also more fan, traffic and echo. In a quiet, furnished room a condenser is fine; in a typical tiled room with a fan, choose a dynamic.
