How to Reduce Background Noise in Remote Calls

In today’s world, remote work and virtual meetings have become the norm. While they offer flexibility and convenience, they also present unique challenges. One of the most common frustrations is dealing with distracting background noise. Whether it’s the barking dog, a noisy street, or chatty family members, unwanted sounds can severely impact the clarity and professionalism of your calls. Fortunately, there are many effective noise reduction tips you can implement to ensure crystal-clear communication. This article provides a comprehensive guide to help you eliminate distractions and enhance your remote call experience.

Understanding the Impact of Background Noise

Before diving into the solutions, it’s important to understand why noise reduction tips are crucial. Background noise can lead to:

• Reduced comprehension: Participants may struggle to understand what’s being said, leading to miscommunication and errors.
• Decreased engagement: Listeners may become frustrated and lose focus, impacting productivity.
• Unprofessional image: Excessive noise can make you appear unprepared and unprofessional, damaging your credibility.
• Increased stress: Constantly battling distractions can be mentally draining for both the speaker and the listeners.

Investing in noise reduction tips is an investment in clear communication, improved productivity, and a more professional image.

Practical Noise Reduction Tips: Your Comprehensive Guide

Here’s a detailed breakdown of actionable noise reduction tips you can start using today:

1. Optimize Your Environment

The first step towards effective noise reduction is controlling your physical surroundings. This involves making some strategic choices about where you conduct your calls.

a. Choose a Quiet Room

Select a room in your home that is naturally quiet and less prone to disturbances. Avoid areas near the kitchen, living room, or any high-traffic zones. A spare bedroom or a home office is often ideal.

b. Soundproof Your Space

While complete soundproofing may be expensive, there are simple and affordable measures you can take to reduce noise transmission:

• Add soft furnishings: Rugs, curtains, and upholstered furniture absorb sound waves, minimizing echoes and reverberations. For example, placing a thick rug on a hard floor can significantly reduce echoing.
• Use acoustic panels: These specially designed panels are highly effective at absorbing sound. You can purchase them online or even create DIY versions using fabric and foam.
• Seal gaps: Check for gaps around doors and windows and seal them with weather stripping or caulk to prevent sound from entering.
• Hang heavy curtains: Thick, heavy curtains are excellent sound absorbers and can block out external noise from traffic or neighbors.

c. Minimize Noise Sources

Identify and eliminate potential noise sources within your chosen room:

• Turn off appliances: Switch off any devices that generate noise, such as fans, air conditioners, or computers that are not in use.
• Silence notifications: Mute your phone and disable notifications on your computer to avoid distracting pings and alerts.
• Inform household members: Let your family or housemates know when you have a call and ask them to minimize noise levels. A simple sign on the door can be surprisingly effective.

2. Invest in the Right Equipment

The quality of your microphone and headset plays a significant role in noise reduction. Investing in good equipment can make a world of difference.

a. Use a High-Quality Microphone

A dedicated microphone is far superior to the built-in microphone on your laptop. Look for microphones with features like:

• Noise cancellation: These microphones actively filter out background noise, focusing on your voice.
• Directional pickup patterns: Cardioid microphones, for example, pick up sound primarily from the front, minimizing noise from the sides and rear.
• USB connectivity: USB microphones offer better sound quality and ease of use compared to traditional analog microphones.

Popular options include the Blue Yeti, Rode NT-USB+, and Shure MV7. Research and choose one that fits your budget and needs.

b. Choose a Good Headset

A good headset can isolate your voice and block out external noise, both for you and the people you’re speaking with. Consider these features:

• Noise-canceling microphone: Similar to standalone microphones, noise-canceling headsets filter out background noise.
• Closed-back headphones: These headphones provide better sound isolation, preventing sound leakage and blocking out external distractions.
• Comfort: Choose a headset that is comfortable to wear for extended periods. Look for adjustable headbands and cushioned earcups.

Examples include the Jabra Evolve series, Plantronics Blackwire series, and Logitech Zone Wireless.

c. Consider a Pop Filter and Microphone Stand

These accessories can further enhance your audio quality:

• Pop filter: A pop filter reduces plosives (the “p” and “b” sounds that can cause bursts of air into the microphone), resulting in clearer audio.
• Microphone stand: A microphone stand positions the microphone at the optimal distance and angle, ensuring consistent sound quality and reducing handling noise.

3. Leverage Software and App Features

Many video conferencing platforms and audio editing software offer built-in noise reduction tips.

a. Utilize Built-in Noise Suppression

Platforms like Zoom, Microsoft Teams, and Google Meet have built-in noise suppression features that can automatically filter out background noise. Make sure these features are enabled in your settings. For example, in Zoom, you can find the noise suppression setting under “Audio” in your settings menu.

b. Explore Third-Party Noise Reduction Software

For more advanced noise reduction, consider using dedicated software:

• Krisp: Krisp is a popular AI-powered noise cancellation app that works with any microphone, headset, and communication app. It effectively eliminates background noise for both you and the other participants.
• Audacity: Audacity is a free and open-source audio editing software that includes noise reduction tools. You can use it to remove noise from pre-recorded audio or even process audio in real-time.
• Adobe Audition: Adobe Audition is a professional-grade audio editing software that offers advanced noise reduction capabilities.

c. Adjust Audio Settings

Experiment with your microphone and headset settings to optimize audio quality:

• Adjust microphone gain: Set the microphone gain to a level where your voice is clear and consistent without being too loud or too quiet.
• Use a noise gate: A noise gate cuts off the audio signal when the sound level drops below a certain threshold, preventing background noise from being transmitted when you are not speaking.
• Test your audio: Before joining a call, use the built-in audio testing tools in your conferencing platform or record a short test clip to ensure your audio is clear and free of noise.

4. Improve Your Communication Techniques

Even with the best equipment and software, your communication style can impact the perceived noise level.

a. Speak Clearly and Slowly

Enunciate your words and speak at a moderate pace. This allows listeners to better understand you, even in the presence of some background noise. Avoid mumbling or rushing through your sentences.

b. Mute When Not Speaking

Practice good meeting etiquette by muting your microphone when you are not actively speaking. This prevents any background noise from your end from disrupting the call.

c. Use Visual Cues

When possible, use visual cues like nodding or hand gestures to acknowledge what others are saying. This helps maintain engagement and understanding, even if there are occasional audio hiccups.

5. Advanced Troubleshooting Tips

If you’ve tried the above steps and are still experiencing significant noise issues, consider these advanced troubleshooting tips:

a. Check for Interference

Electronic devices can sometimes interfere with audio signals. Keep your microphone and headset away from other electronic devices, such as phones, routers, and power cords. Try different USB ports or relocate your equipment to see if it resolves the issue.

b. Update Drivers and Software

Ensure that your microphone, headset, and audio drivers are up to date. Outdated drivers can cause compatibility issues and performance problems. Similarly, keep your video conferencing software updated to the latest version.

c. Contact Technical Support

If you’ve exhausted all other options, consider contacting the technical support for your microphone, headset, or video conferencing platform. They may be able to provide specific troubleshooting advice or identify hardware issues.
