Precision-Tuned Podcast Clarity

Introducing the CPA unit: A game-changer in podcast acoustics, optimized for the 80 hz to 6,300 hz range crucial for male voices. Designed for versatile spaces, this movable unit combats thin recordings and, with seven units spanning 170 sq. ft., showcases enhanced voice clarity and speech intelligibility, factoring in reverb, mic types, and room sealing.

CPA: Versatile Acoustic Solution for Podcast Rooms

Podcast rooms are everywhere. They are in bedrooms, basements, and even garages. They are usually a temporary set up in an existing room that is not treated with any acoustical goal. With these dual usage rooms, one needs a treatment type that can be easily put into place and removed or relocated when needed, yet be powerful enough to reach down into that 80 hz. region and upward through 6,300 hz. Our CPA unit is designed for this exact frequency range and it is available in a freestanding unit. The units shown in this project are prototypes and we are testing for performance, size, and ease of movement so the end user can use the room for multiple purposes.

The acoustical goal is to reduce the energy from 80 hz. – 6,300 hz. This frequency range treatment works the best for male voices. Using foam technology, we have a starting point for a 2″ thickness of 125 hz. We need to go lower in order to capture the real fundamentals of male voice. If you listen to most podcast recordings, they sound thin in this frequency range because the treatment they are using does not start low enough or get enough. In order to capture the full fundamental of male voice, we must get down into the 80hz and up range. We must also be able to extend this response range smoothly and in a linear manner. No spatial irregularities in the absorption treatment curve.

Product positioning is also critical. In this podcast room, we have 7 units total @ 48″ x 72″ x 6″. We have one unit behind the desk, one unit overhead and one unit to each side of the desk. The remaining three units are positioned around the audience area. See the graphic for exact positioning. The total square footage coverage is 170 sq. ft. which is the calculated square footage requirement to get reverb times down so we can support speech intelligibility indexes. Remember it is always TAP when it comes to voice and music. It is using the correct type along with the proper amount of treatment in the proper position within the room.

Acoustic Foam StudioPro Performance

Our StudioPro Acoustic Foam is a premium product designed for audio professionals and enthusiasts seeking superior sound quality in their recording or listening spaces. The foam boasts a smoother absorption curve from 125 Hz to 500 Hz, which is essential for capturing the heart of vocal and music frequencies. It offers more absorption below 250 Hz than standard foams, with 30% at 125 Hz, 63% at 250 Hz, and reaching 100% at 500 Hz. This technology is specifically engineered to manage side wall reflections, allowing for the direct sound from sources to be heard clearly without the interference of room reflections. Made in the USA, this acoustic foam is used by award-winning audio professionals and is a significant upgrade from ordinary insulation or standard studio foams.

CPA – Ceiling Perforated Absorber

The CPA – Ceiling Perforated Absorber from Acoustic Fields is designed to address the common issue of unwanted axial modal pressure in small rooms with ceiling heights of 8′, 9′, or 10′. This pressure can lead to a significant dip in the frequency range of 60 – 75 Hz, which is particularly problematic for audio quality. To combat this, the CPA utilizes a lightweight yet effective technology that incorporates Acoustic Fields’ proprietary foam, increased to a thickness of 6 inches. This foam is housed within a perforated absorber structure, with a front plate featuring 1/4″ diameter holes spaced 1″ apart, to effectively absorb frequencies down to 65 Hz. The CPA’s dimensions are 48″ x 6 1/2″ w x 76″ l, and it weighs 75 lbs, making it suitable for suspension over the Digital Audio Workstation (DAW) in a studio setting.
