PCD Hires “@PKaudiovisual” As New Engineering Manager

The following press release was originally posted on the PCD blog

SANTA ROSA, CA – PCD, Inc. ( is pleased to announce that Paul Konikowski, CTS-D has joined the NorCal firm as the new Design Engineering Manager.  Paul brings a wealth of knowledge of the AV integration industry, as well as real world experience in live event production and information technology.

Paul’s career started in information technology with a co-op position at Critikon, a medical device manufacturing company owned by Johnson & Johnson. Performing a mix of help desk functions and network wide system upgrades, Paul learned the value of good customer experience (CX).  Paul supported about 200 users in everything from Microsoft Windows and Office migrations to printer maintenance to mainframe server data backups.

After graduating from Georgia Tech in 2001 with a Bachelor’s degree in Computer Engineering, Paul shelfed his computer skills for few years, and decided to become a “sound guy”.  Starting at the bottom, pushing brooms, driving trucks and stacking speakers, he quickly learned the technical ins and outs of live audio reinforcement from veteran sound engineers at Snow Sound and other live sound companies.

Since 2004, Paul has worked in audiovisual integration and unified communications. At North American Theatrix, he built equipment racks and installed loudspeakers, PTZ cameras, video projectors, flat panel displays, and other AV components for theaters, casinos, hotels, schools, aquariums, and museums.  He obtained his Infocomm CTS certification and went to work for HB Communications as an Associate Engineer, learning AutoCAD and AV system design, and then obtained his Infocomm CTS-D certification.

In 2007, Paul decided to relocate from Connecticut to California and became the Senior Consultant at Rosen Goldberg Der & Lewitz, a smaller consulting firm who specializes in architectural and environmental acoustics in addition to traditional AV design and engineering.  As the local market shifted from consultant-driven construction to design-builds in existing buildings, Paul decided to move from consulting back to integration, joining Snader as a Systems Design Engineer.

In 2011, Paul began freelancing, doing business as PK Audiovisual.  He continued to do AV design and engineering, but also moved into social media, technical marketing, blogging, advertorials, whitepapers for consumer electronics, wireless home theater speakers and mobile devices. By becoming a blogger and online content writer (oftentimes ghostwriting), Paul helped to bridge the gap between audiovisual technology providers, AV consultants, equipment distributors, systems integrators, and end-users.   Over the next 5 years, Paul took on a number of clients including, Arcata High School, HDMI, MHL and WiSA, and then worked full time as a Technical Marketing Engineer with Starin, an AV distributor, hosting online training and visiting consultants and integrators.  It was during this time that Paul started working a lot of industry trade shows like CES, ISE, NAMM, and CEDIA.  In recent years, Paul has worked full time as a Multimedia Solutions Architect for Strategic Products and Services, and part time for RGD Acoustics, Zoom, and Creation Networks.

As the new leader of the PCD engineering department, Paul will work as a “player-manager”, delegating projects, while taking on his own large scale projects. By leveraging his engineering background with his consulting experience, he leads the PCD engineering team, implementing large scale audio-visual systems, initially awarded through the “Design-Bid” and “Design-Assist” processes. PCD is also a full service “Design-Build” integrator; recent projects include performing arts centers, universities, schools, sports stadiums, corporate telepresence, houses of worship and more. Paul’s main goal at PCD is to maximize efficiencies in the engineering department, delivering quality drawings and products, meeting all time commitments, and building long term relationships with audiovisual consultants and other business leaders in the San Francisco Bay area.

Bill Graham, PCD Director of Operations, is working with Paul to build up his team of engineers.  If you or someone you know is looking for work in wine country, please check out the Careers page on the PCD website ( for more information about these exciting openings.


Acoustical Consultants

Acoustics For Critical Listening Environments

Tavius Aiton, Architectural Acoustics

Guest blogger Tavius Aiton has worked in audio and acoustics for the past decade, from design and sales, to project management. Tavius is owner of Architectural Acoustics in San Jose, CA.

The solution always begins with understanding the problem. Acoustically, client expectations and needs are defined most by the purpose of their space. Obviously, budget and materials finishes factors into the equation as well; but in critical listening environments, acoustics should drive the design and budget.

Acoustics are best handled in the design phase of new construction.  Any critical listening space should first be optimized for shape and size, defined by its intended purpose, speaker orientation and patterns, as well as listening positions. Often, noise must be contained within a space, as well as isolated from outside. Wall, ceiling and floor construction design are important for sound and vibration isolation issues from adjacent spaces.

In rooms with shared walls needing isolation, choosing the proper stud type and configuration are important. Often, more floor space is required as there is greater airspace and less connection points between the walls. Double stud, or staggered stud layouts are often considered along with insulation. Isolation clips can be applied on rails across the studs to further isolation.

Early incident reflections may be desired in many critical listening spaces, but this needs to be carefully considered, because too much reverberation reduces speech intelligibility and musical clarity.  Ideal reverberation times should be called out by consultants.  Absorptive materials, or porous materials, allowing flow resistance of sound energy, can reduce reflections by frequencies depending upon type of material, thickness and airspace or backing material.

Reflection can be important, especially in larger spaces. Early incident sound reflections can be redirected to listeners prior to the room “coloring” them due to longer reverberation times.  Often, sound energy is redirected specifically based on size, shape, and type of materials placed throughout the room. Diffusion, or even-scattering of sound reflections, can be a necessary consideration in controlling the sound level equality throughout a space and maintain sound integrity.

Critical listening spaces require many considerations.  The earlier an acoustical consultant is brought in on the job, the better.  Often this can avoid acoustical issues that may be difficult, or more challenging, and costly to consider later.  Its also important to have a qualified contractor to implement the consultants design criteria, by properly installing the acoustic treatments, and remaining within budget.

Often budgets include high end equipment, and little to no acoustical treatments.  This is another reason to hire the appropriate consultant from the start: to have all the acoustical requirements laid out and included in your budget.  Ensure the most affective and affordable solutions for your acoustical or noise reduction needs. Make the most of your critical listening space and the investment in time, energy, and capital!

I would be happy to recommend a consultant specific to your needs.
