In this video, Dennis Foley dives deep into the study of room modes, specifically focusing on how they manifest in small rooms. Utilizing a real-time analyzer (RTA), Dennis demonstrates how you can visually and audibly detect distortions in room acoustics, particularly within the challenging sub-100 Hz range. By examining a persistent 80 Hz room mode in his own studio, Dennis illustrates the practical steps needed to identify and correct these acoustic anomalies. This tutorial is perfect for anyone looking to understand and improve the acoustic performance of their space. Follow along to learn how to use an RTA to enhance your acoustic troubleshooting skills effectively. - วิทยาศาสตร์และเทคโนโลยี
This was incredibly helpful. I downloaded a RTA from Google play store. Ran it with a particularly muddy bass song. Saw 3 modes in the 70-130 Hz range. Using Roon built in EQ, i put in steep notch filters. It made a huge difference.
Question- do you have a video talking about the difference in results between room correction vs treatment? I've heard it said room correction can only take away.
I appreciate what you do. Your solutions are so much more effective and better value than the other offerings out there.
This is one method. However, it comes at a cost. Reducing the energy at certain frequencies from the original source material has a direct impact on the harmonics of those frequencies. If you reduce the fundamentals, you reduce the harmonics. It is always best to minimize unwanted pressure levels within the room through treatment if higher resolution is your goal.
I also have a rack mounted spectrum analyzer in the signal path to visualize what’s coming from the source versus what the room is producing. Good tip.
Watching and listening to sound at the same time go hand in hand for understanding.
I am fond of REW, rarder to ser up, but the information available is mind blowing..
Watching real time movement of sound energy will go a long way to understanding your room issues in real time. After you have an understanding of the octave bands and their movement, you can then integrate treatment.
Excellent information. Is there a particular RTA or RTA software that you find works better than others that you’d recommend? Also, are the umik’s good enough for RTA duty? Thank you for the time and effort you put into these videos
Thank you. RTA Pro Apple store
Lol! I recognized it last week! Completely blew me away...
Use an RTA to give you a visual picture in real time of how sound and room interact with each other. It will go a long way towards your understanding of the proper treatment types to use.
@@AcousticFields Yes sir! Thank you!
I have a similar problem, my ceiling is pretty well treated, should i work on the floor?
In most rooms we do, treating either the floor or the ceiling is sufficient. We rarely have to treat both. Remember to treat 80Hz. you need a minimum of 6 - 8" of space.
@@AcousticFields My bad, i have a null around 80, peak is at 35 which GLM calibrates well. It's the silly nulls that kill me :(
@@dronbana All modes are predicable and consistent always based upon room dimensions. This predicatbility and consistency allows for effective treatment to be applied correctly that has the proper rates and levels of absorption for music and voice. Always rememeber that music and voice requires proper rates and levels of absorption to not blur and smear the harmonic orders. Everything in small room acoustical design and treatment should be harmonic sensitive. The first four harmonic orders must be heard at a minimum.
@@AcousticFields Thank you for explaining that, i appreciate it 🙏
80 Hz, is that a 7 foot ceiling?
It is produced by 7 - 8' distances.
