Thank you. I've recently had to work with a voice over artist who bought recording equipment for a home setup, due to the pandemic. His recordings were awful, sounding like a Zoom call. I made him double check that he was using the correct microphone and he was, so he moved to another room (I think the bathroom). I didn't have the heart to tell him his work was rejected, but I think I should advise him on creating a good recording space, or maybe you could point me to a video I could send him. Many thanks for your great advice, I have learned so much.

Unfortunately for me and I'm sure for a lot of people listen rooms are also living spaces, so things like couches, coffee tables, and lamp tables plus lamps are things we can't get around, not to mention other factors of should I say factor ;-) Even so I think my/our space sounds pretty awesome, but know can be better if it was dedicated 100 percent. Last I heard "panels' will not be tolerated :-( I feel like such a wuss right now but such is life! Thanks Again and Happy Listening!!

[@AcousticFields]

Living and listening in the same room produces a series of compromises that usually have a negative impact on the sonic presentation value.

[@hokatichenci]

For speakers in corners - aren't subwoofers the exception to the rule here? I was always taught subwoofers are best the corner spaces since the waves are so long that the reflections from a corner can start to cancel out.

[@AcousticFields]

Placing a low-frequency energy device in room corners increases the output of the subwoofer. However, the increased output is room distortion. When will people realize that quantity is not quality.

[@hokatichenci]

@@AcousticFields interesting! I had read that in the Master Handbook of Acoustics back in the 2000's so interesting to see how times have changed.

[@benjaminlockhart5686]

Awesome!!

Thanks!

Clearing sound field in a mixing room I'd have to use higher speakers stands. That will result in a more aggressive tilt to the monitors. Will that cause problems?

[@AcousticFields]

Speaker stands are always recommended especially ours where they contain our carbon technology so you gain low - frequency absorption along the front wall where pressure is the highest.

Hi! I see you are a true expert in the field of acoustics. I have a question: if I put cheap Amazon foam on top of the mineral wool panels I am going to build (it is all I can afford for now), will the 1" foam interfere in the absorption of my mineral wool panel? The reason I'd put foam on top of it is that someone in my family is worried the Muslin fabric wont be enough to prevent the mineral wool's particles to escape the panel, so they want me to add a thin layer of acoustic foam to make sure no particles passes through the muslin and end up breathed in while I sleep, but I fear the foam will interfere with the mineral wool effectiveness. Would it?

[@AcousticFields]

The panel depth using limp mass material types determines how low the unit will absorb to. Do not use building insulation. It lacks the proper rates and levels of absorption for music and voice.

[@paulhunter6652]

Great information. How much will room correction such as ARC in Anthem amps or Dirac built into the amplifier help deal with alcoves, or an L shaped room?

[@AcousticFields]

No, these systems work on predictable and consistent room boundary surfaces.

[@paulhunter6652]

@@AcousticFields Thank you for your reply. Many sales people and actual ARC and DIRAC users who have set their systems up say different. Some say they turn off the room correction for music listening two channel. Dirac may be better than ARC. I know you defend the room but at the end of the day I have to have music. Few have the perfect room set-up.

In a room size of 9 feet long by 10 feet wide how will I but my home theater speakers if not in corners

Low-frequency management first and foremost.

@@victorpulos823 you can submit your room info with pics on their site. Check out the Acousticfields Sam Small video, that should give you an idea. I think its in the "Projects" section of their site too.

stereo rack between speakers is the same height as speakers.

Wow, very nice. Very nice indeed. Thank you for your support and following.

What are the reflections produced from this rack called?

@@donaldpump1282 it is behind the speakers though. there will be no primary reflection from the table

Getting quality sound in a room is all about doing a lot of little things correctly. Just as important is doing them in the proper sequence or order. Every small action taken is like one step in a staircase. If you take each step in the proper order, you will reach the top of the mountain as the Brit's say. The elevator to good sound is out of order. You must take the sonic stairs one step at a time.

[@6stringsandapick]

Cupping your hands around your mouth is such a simple but effective demonstration. It is so easy to hear the impact I don't know why more people don't understand. High quality headphones would be better IMO.

[@AcousticFields]

Headphones are very small rooms. In fact, their nickname is "cans". This experience in a can is completely different that room sound.

Obtaining maximum resolution is all about resolving the numerous variables of pressure, reflection, and noise transmission.

another depressing video.

[@AcousticFields]

Don't be depressed. Spend that emotional energy on fixing the emotion of your room.

[@paulhunter6652]

Yes. I have the dreaded alcove however when I move the speakers out they sound a lot better. Thinking of investing in more headphone gear or move…
