Noise Cancelling Wall Panels

There is no such thing as noise cancelling wall panels. There is no wall panel you can use for noise transmission issues. Noise is like water. It will find the weakest link and go through that. If there was such a thing as noise cancelling wall panels because noise can not be cancelled. It can only be reduced or mitigated through a proper barrier design. When you are dealing with noise issues, you must build a barrier.

Mitigating Morning Noise with Barrier Technology: Understanding Frequency and Amplitude Measurements

A barrier is a structure that you build to place between the noise source and you as the receiver. It is a structure that mitigates the garbage truck noise at 6 am. There are no noise cancelling wall panels since any barrier design and build is a permanent build. Any time you are discussing noise cancelling wall panels or any barrier technology that is associated with noise, you must measure the frequency and amplitude of the noise.

All noise is composed of frequency and amplitude. Frequency is where the noise lies on the human hearing scale and amplitude is how strong each frequency of noise is. The frequency tells us what barrier type we must build. If our noise issues lie below 125 hz., we will need to design and build a barrier that is dense and has mass. Lower frequency noise issues require barriers that are usually made out of brick or concrete.

Designing Efficient Barriers for High-Frequency Noise Reduction: The Importance of Measuring Energy Transmission

Noise that has frequency and amplitude issues above 125 hz. requires a thinner barrier that has less mass, takes up less space, and has a lower cost and space requirement than building a barrier to mitigate noise below 125 hz. This is why all noise must be measured for a one week time period. This measurement strategy will show us what day the greatest energy transmission issues exist. When we are designing the appropriate barrier for any noise issue, we want the maximum day pressure so we mitigate as much of those frequencies as we can. This barrier design also will manage the lesser pressure days.

All barrier designs are composed of many material types. Each material type has a particular density or mass. Each material type is arranged in a sequence of order with other material types. The particular frequency determines the material one uses. The amplitude or strength of each frequency determines how much mass or how thick the wall will be. We have been building barriers at Acoustic Fields for 30 years.

Choosing the Right Barrier Design for Effective Noise Reduction: Factors such as Frequency, Amplitude, and Cost

Most barriers rank from 6″ deep up to 18″ deep depending on the frequency and amplitude of the measured noise. When noise measurements are taken, we look at all noise below 125 hz. Noise issues below 125 hz. require a completely different barrier design that has mass, takes up large amounts of space and is expensive. Noise above 125 hz. takes a completely different barrier design than noise below 125 hz. Noise transmission above 125 hz. is usually for voice. Voice transmission can be reduced in much less space, materials, and cost.

All noise must be measured over a seven day time frame. At Acoustic Fields, we have apps that we send to you and you download them on your phone. You take frequency and amplitude noise readings twice a day over a seven day time period. You will take readings during the quietest part of each day and the loudest part of each day.

Measuring Noise for Custom Barrier Design: A Seven-Day Procedure with Acoustic Fields

You will record these numbers on our online data sheet. After a full week of measurements have been taken, you will send the data to us. We will design the barrier that you will build that will specifically deal with your noise transmission issues. We will send you a graphic drawing showing you how to build the barrier and install it. You can use a DIY approach or submit the drawing to contractors for building. It will be 100 % fixed and 100 % right.

Building Effective Barriers for Noise Reduction: Importance of Accurate Measurements and Permanent Construction

Noise measurements are a must when you are dealing with noise issues. You do not want to spend one dollar more than you have to with noise since barriers are a permanent construction build. You must build the barrier using standard construction techniques and materials. There are no noise cancelling wall panels that you can hang in your room that will stop noise transmission.

All barriers must be a permanent construction build. You will not be able to move and take your barrier with you. This is why you must follow the old carpenter adage of measure twice and cut once. Once you have all the noise data and we send you the barrier design you can begin the build process. Make sure if you have large noise issues, you have the appropriate budget to resolve your noise issues.
