Let’s keep this simple: using computer simulation, we examine a room, identify unwanted noise (echo), and together we develop a plan to control it.

If your room has too much echo or you plan to build a new room and want to get it right read on…

Reverberation Control

Reverberation is sound that is heard long after the “original” sound ends (i.e. echo in a gym). An echo over 2 seconds can be distracting and compromise speech clarity.

Listen to this audio recording with and without echo:

With the aid of computer modeling we SEE where these echoes travel (Fig.1), develop a plan to reduce their reflections and ensure the finished treatment looks like an architectural feature (Fig. 2).

Mechanical Systems Noise

Hums and buzzing when lights are dimmed, or rumbling sounds when air-conditioners turn on/off are annoying and distracting.

Were these problems exist, or on new construction projects, we examine Electrical and HVAC plans (volume/air speed, duct size/configuration, diffusers/return size/duct silencers) to correct it.

Yes, mechanical silence is golden!

Stage Volume Control

Have people complained “I couldn’t clearly hear the worship leader when he/she sang” or “Does the band have to play so loud?”

Think big picture for a minute…

  • Are the walls and floor that surround your musicians made of hard or soft materials?
  • How big and how many monitors are on the platform?
  • Do you have musician amps not controlled by the soundboard?
  • Does your worship team perform sound checks before your worship service?

Let’s agree there’s more contributing to loud platform volume than just the drum kit.

Before you spend money on quick fixes, give us a call. The solution might simply be trading-in those large Rock ‘n’ Roll monitors for smaller units or training your technical team on proper pre-service sound check protocol.

If you are building a new worship space, good stage planning (Fig 5 & 6) and an acoustic study should be high on your design phase list. Believe us, you can afford this service.
