A seminar/ Webinar on room acoustics and placement of speakers

[matbhuvi]

Count me in as well.

 

[nmursekar]

Have any dates or days finalised for webinar?

@ Bhagwan.

If you are looking for a larger room (class room type) for more people participation, i can check with my society clubhouse if they can spare a hall for one session for a nominal fee on a weekend. The location will be @ Thane.

This is great, I have been looking for Hifi meetups, but couldn't find any good one. Good start.

 

[sathiamoorthy]

Sir any updates?

 

[MJ23Bulls]

Can someone suggest some more names to take up the role of presenter?

Sometime back I had read one FM CMS Sajith's thread on his HT acoustics treatment. There should be a thread by him too, in DIY section, I guess. He should be knowledgeable enough to share his own experiences.

I think you are referring to cmsajith.

With due regards to Sajith's knowledge on the subject, to be able to explain about accoustics, one has to be a professional with lots of hands on experience IMO. Else one may not be able to do justice.

BTW, I understand that he has gotten busy with his own affairs and is not very regular on the forum. The last post made by him was on 7th March 2014: http://www.hifivision.com/speakers/...inting-performance-kef-q300-2.html#post574764

He last visited the forum on 21st January 2016.

Sir any updates?

Update:

I've been given to understand that FM sdurani is unable to commit because of his busy schedule.

FM Manoj is also busy but has promised to get back with convenient date. Looking forward.

Sorry for the long delay folks. FM Manoj has made some effort and was able to make a list of the topics that would be discussed. Here they are:

1. speaker placement
* general guidelines
* reflections
* soundstage
* sbir
2. Room Modes (advanced)
* Width, height and length
* Seating location
* speaker placement and effects on modes
* Room modes - ways to minimize effect
3. Room treatment (Not sure if this is needed)
* diffusion or absorption
* guidelines about absorption.

Feel free to come out with suggestions on additions/ modifications to the topics mentioned above.

I personally feel that these things are best done in person.

I personally feel, audio can only be experienced it cannot be spoken about without live demo. If I talk about a thing & you cannot hear / feel / experience it - what is its use ? It would be hollow.

You sure have a point there Bhagwan. Physical sessions would be the best. Having said that, considering how wide apart are the participants located, it is well neigh impossible to bring them all together at one location. I was just making an effort to make a beginning so that theory can be covered atleast.

Those participants in Mumbai who are interested to attend a physical seminar at Mumbai can indicate their interest in this thread so that it can be taken forward as well.

Let 5 or 6 members send in pictures or drawing of their room with current placement. Let the experts suggest solutions for improvement. Concerned members can then implement the suggestions and report.

This will make the seminar more relevant

I agree. Practical knowledge and application will be far more useful than the theory which is readily accessible.

 

[captrajesh]

Wonderful idea Prem! My setup is temporary and going to be relocated shortly. I solicit other interested members to post pics.

It would be great if a brief topic about 'Phase Response' is too covered.

Hi Capt

I am also interested to join this Webinar. Nice initiative and Thanks for that.

Are you referring to Phase Response in speaker designing?

If so, I'm not sure if it would fit into the topic under discussion i.e. Room acoustics and placement which is purely for beginners.

No I am not referring to Phase response of speaker but of the speaker + room. IMO speaker placements are all about how we are able to manage the acoustic phase of the speaker system and the room. By moving the speaker in the room we are not doing anything to the frequency response but only altering the phase so that it sounds right at all positions without any sweet spots.
