Help with calculating treatment volume for room with vaulted ceiling

[resqguy]

I have had good success with my own HT room setups for more than 20 years. I have studied and followed the tools that are available for room response and measurement. Lots of incredible innovation over the years.

It is time to focus on my HT listening room. My listening room is ~22ft x 40ft with a 22ft x 28ft section (listening area) vaulted. The base ceiling is 9ft and the ridge height is ~17ft. The ceiling and end walls are currently all drywall and make for a very lively (echo) response. My concern is the frequencies in the mid and upper range. I normally use AMROC for treatment calculations but it is set up for rectangular rooms with flat ceilings. I am looking for an alternative way to calculate the amount of treatment needed to reduce the amount of echo coming from my vaulted ceiling.

My HT system is designed for large rooms, plenty of power and (speaker) drivers to cover.

TIA

Have you taken measurements yet to see where the issues are outside of the spreadsheet? Those calculators, like AMROC, are useful a lot of times, but are no substitution for measurement software in rooms with a lot of variables.

I haven't taken measurements yet but the echo is really apparent just from normal conversation. I actually have had the opposite experience. I find the measurements reinforce the calculations. I spent hours measuring the bass response once only to find that the calculations were spot on. After making the corrections I confirm the results with REW. It is just a different approach where I use the calculations for the major corrections, then fine tune with measurements. In this case I will apply sound panels based on calculations then use drapes and room accessories to dial in from there.

Kudos for using the available tools and evidence based approach to this. You'll fit right in here. Welcome to the forum!

Echo being apparent just from normal conversation implies a pretty darn lively room. Is this room currently empty, devoid of furnishings and decor? Carpet/rugs or hard floors? Such huge, lively rooms seem to beg for speakers with more controlled directivity, so curious about what you're working with, as well as the room and what stage you're at in this project. Got pics or more details to share?
