How close to the real thing?


Recently a friend of mine heard a Chopin concert in a Baptist church. I had told him that I had gone out to RMAF this year and heard some of the latest gear. His comment was that he thinks the best audio systems are only about 5% close to the real thing, especially the sound of a piano, though he admitted he hasn't heard the best of the latest equipment.

That got me thinking as I have been going to the BSO a lot this fall and comparing the sound of my system to live orchestral music. It's hard to put a hard percentage on this kind of thing, but I think the best systems capture a lot more than just 5% of the sound of live music.

What do you think? Are we making progress and how close are we?

Comparing sound pressure from a live instrument in your room,at home,is not accurate for this comparison.Sure these instruments have a lot of volume,but when you listen to them live,figure the room volume of the building,and compare it to your listening room volume.The volume difference is huge.Who would want the actual drums in your home?The smart drummers use headphones,when performing.A lot of the other musicians wear ear plugs too.My neighbors Baby Grand gets to loud,in an(approx),40x25x12ft high room.A violin gets extremely loud.These live instruments do cause hearing damage.At home,we can control this.Another plus, for listening at home.Correct what you can,that's wrong with your system. Anything that draws attention to itself, especially anything offensive.The weak link I mostly find now is,the quality of the recording,not the system.After you've done corrections,get some good recordings,sit back and enjoy.
I agree cone area in addition to overall driver quality and build, optimal power delivery, and ability to pressurize air as a result is key to getting dynamics out of a playback system that can compete with the original instrument(s) in a similar room configuration.

This is one of the reasons I am a big fan of Walsh drivers. Drivers applied using the Walsh principles where sound is emitted from the rear of teh cone omnidirectionally benefit from effective application of available driver surface area, and the omnidirectional aspect results is a sound dispersion pattern more like that of a real, un-amplified, acoustic instrument. To get similar results with conventional driver technology generally require much larger designs and drivers that bump up the cost to deliver substantially.
Hi Hifihvn,
Drummers wear headphones because they are mic'd and are using the headphones as monitors. Drums get very loud, up to 110db. I have not heard any strings that can cause hearing damage. Granted most of my live listening is to cello and violin & piano and it is in a venue capable of seating 600 people, but as I stated earlier, I run a sound board fairly regularly. I have never been subjected to threatning levels from these instruments.. and I do tend to duplicate spl's at home vs live(non amplified) venues. The peaks are short term and is required to really get the dynamics that have been discussed here. I completely agree that the wink link is the recording. Good Listening, Tim
"I completely agree that the wink link is the recording. Good Listening, Tim"

The recording being the weak link is where a good audiphile wants to be. That is one thing that is not in his/her control.
Hi Timlub,A lot of musicians have been aware of themselves being at risk for hearing loss.Schools of music teach them about this also.The headphones and plugs I was referring to,were the passive ones that they can hear what they need to,without amplified headphones,or plugs.It depend on the situation as you most likely know dealing with recording,or mixing for amplified music.A violin can reach 110 db at their ear.Wind instruments can get high also,plus a lot of others.It depends on the instruments too.But instruments used for concerts are the ones that are chosen for volume, along with their sound quality.There are some that say some of the lesser wanted instruments,may sound better, but just can't produce any volume,to qualify for a concert quality piece do to this.Some wear those plugs with holes in them(I think),that claim to let enough frequencies through for them to perform correctly.A couple of links for sound pressures.I'm guessing the music schools might have accurate info on this,plus Google.I like live music,we need it for our recordings,but we can do fairly good at home listening,for great enjoyment also.The last one may be conservative for db ratings in certain cases.Links.[http://www.hear-it.org/page.dsp?page=1662][http://www.sengpielaudio.com/TableOfSoundPressureLevels.htm][http://www.gcaudio.com/resources/howtos/loudness.html]
