Church Acoustics: 5 Biggest Challenges and How to Fix Them

Many churches struggle with acoustics. With a small-to-medium sized church, you may not have the budget to hire acoustical engineers or sound designers for your worship space. So, what's a church to do?

In this post you'll discover 5 common acoustic challenges facing most churches. You'll also learn about 5 acoustic solutions that can be implemented by your tech team to improve the overall sound quality in your church.

5 Common Acoustic Problems in Churches

  1. Outdated building design. The acoustics in the church may have been designed for unreinforced sound. These types of spaces often lack clarity when it comes to reinforced music and amplified speech. (This is common in older churches designed for traditional liturgy and congregational signing.)
  2. The stage area is too reverberant. This causes muddy sounds on stage and a lack of intelligibility for the congregation in front of the stage. This problem is made worse when using traditional stage monitors and guitar amps on stage.
  3. Hard flooring and seating surfaces. Hard surfaces are acoustically reflective, which means sound waves bounce off the surfaces and reverberate throughout the space.
  4. The room is too symmetrical. Parallel surfaces cause sound waves to cancel each other out or create acoustical nulls. Direct reflections off of the back wall can also cause issues on stage. (In general, acoustics in a worship space should not have parallel surfaces, especially on the back wall or behind the stage.)
  5. Excessive noise or vibrations from mechanical equipment and ducts. Acoustic energy from the sound system can cause vibrations or resonate within heating and cooling system ducts. Fans can also add noise into the room, raising the overall "noise floor" of the space, requiring the sound system to be turned up.

Top 5 Acoustic Fixes for Churches

Acoustic Fix 1: Acoustical foam panels placed in key locations around the room help control high frequencies and surface reflections. These are available in a range of sizes to accommodate different rooms and environments. They also come with an adhesive backing or can be mounted on tracks for easy installation. A variety of colors are available to complement the design of the room. Use acoustic foam panels near windows or doors where there is less than ideal absorption qualities in the wall material.

Acoustic Fix 2: Acoustic curtains or blankets are an effective and inexpensive way to reduce reverberation. You can hang them from ceiling rafters or use on a track system for easy installation. This type of solution helps manage high frequencies by dampening them with acoustical fabric that's flexible and easy to install.

Acoustic Fix 3: Acoustically transparent panel covers are more expensive but easier to maintain. Instead of acoustical foam or exposed acoustic insulation, these panels have sound-absorbing material sandwiched between two pieces of fabric that's printed with patterns and colors on one side only so the front surface is acoustically transparent. These can be hung from ceiling rafters, mounted on tracks like acoustic curtains, or placed in portable frames.

Acoustic Fix 4: Sound diffusers work to scatter sound waves in a room so it doesn't create echoing reverberation by reflecting off the walls. Diffuser panels can be designed to work for both mid-frequency and high-frequency problems. For low frequencies, consider using bass traps to minimize standing waves, which are created by bass energy building up in particular areas of a room, typically in corners.

Acoustic Fix 5: Get rid of hard flooring by using carpet runners or pads on the stage area or in aisles. Consider replacing unupholstered church pews with chairs that are padded so they don't reflect sound waves back into the room. Using carpet or area rugs is a great way to control reflections, but sometimes the design of the space doesn't allow for carpet. Vinyl flooring with acoustic underlayment can also be used with some success. In general, the thicker and more padded the material, the better the acoustic performance. Laminate and concrete (especially painted concrete), for example, are acoustically reflective so they're not ideal flooring choices for most churches.


Church acoustics problems can be difficult to diagnose and address. Fixing these problems can be a multi-step process that might involve installing acoustic panels on walls or hanging acoustical curtains from rafters, inserting diffusers or bass traps at strategic locations around the room, using floor materials that reduce reflections such as carpeting and area rugs, or rearranging the seating area.

Want to save time and money on your church acoustics fix? I highly recommend consulting an acoustics professional prior to purchasing material, even if you plan to do the work yourself.

Addressing your church acoustics will offer improved sound clarity for amplified speech and music, less reverberation and echoes on the stage area (leading to better vocal intelligibility), reduced resonance caused by mechanical equipment or HVAC ducts, lower noise levels and fewer worship distractions for your congregation.
