Is it possible to know the maximum db output of a pair of headphones based on your laptop volume

Hello all, I just joined the forum on advice from r/audioengineering. I asked this question over there and they thought you would be better to answer.
My question is fairly straightforward (may not be simple).
Is there a way to know the maximum db output of a pair of headphones (such as SONY MDR 7506) at a set system output on a macbook pro (for example 4 bars)?
Ideally I would like to know that the headphones cannot exceed a level (say 75db) no matter what I throw at it. Then I can set the volume level of the mac, and stop worrying about headphone volume for ear damage.
I produce music on my laptop for hours on end and the volume of the sound can vary widely quickly when different effects and sounds are introduced.
I know there are headphones that limit the db output, but the limit is too high (usually 95 or 100 db) from what I have seen.
Thank you for your help (if possible)

This is a difficult question to answer with any exactness as it depends on a number of factors. Program, test phones sensitivity/resistance...meter response/calibration...etc...
I just did a quick measurement on a pair of 7506's using a phonic tool with program (classic rock) at ear cup, unweighted. with program approx. -5 bars on the "volume display" was approx. 75db
With pink noise approx -6 bars about a 75db average (you can subdivide each bar by 4 using shift+option)
Max w/pink noise 88db.
This was all sourced from iTunes with the volume on iTunes all the way up.
Keep in mind this was quick and dirty, but may give you an idea. As I mentioned before there are a ton of variables involved, and this was done quickly.
Hope this helps you some.
I should have also mentioned that this is db SPL, and I had the mic in between the cups to iso it from some ambient noise. I don't know if all the machines are alike in output and gain structure.

Possible to know the URL of page while within the working iWeb on desktop?

Is it possible to know the URL of any page in a website by looking at the working iWeb copy on the desktop? I made my website over a year ago and used iWeb '06 and cannot remember that far back. Now I am using iWeb '08. I keep getting SORRY messages when I hit the VISIT button.
This is making me nervous.

Anybody know the maximum channel, concurrent connection limit

Anybody know the maximum channel that can be set and the maximum concurrent connection that listener can support for WebSphere 6.0 Solaris.
One more question, please correct if I'm wrong; in order to set above value, I have to modify qm.ini as below:
TCP:
Port=1414
KeepAlive=YES
ListenerBacklog=800 --------> for maximum concurrent connection that listener supports
Channels:
MaxChannels=1000 ----------> for maximum channel for QManager
MaxActiveChannels=1000
Every suggestions would be appreciated.

Not really sure what you mean by "half-closing" and the question you're asking. Can you clarify?

Is it possible to know the memory location of a variable in java

Hai all,
i want to know the memory location in which a particular variable is stored. is it possible to know in java.

I just wanted to test the internal processing of the
string variable when we want to change the value of a
string variable. i heard that the variable will point
to a new reference once we change the value of a
string variable. so to test it out i want to know the
memory location of a variable before and after
changing a string variable.You can use the operator == to perform similar tests.
String a;
String b = a ="hello";
a += "world";
if(a==b)
System.out.println("They are the same object");
else
System.out.println("A new object was created.");
}

Is it possible to know the file name of images loaded?

Hi:
I have a folder containing some images named 01_image_name.jpg, 02_image_name.jpg, 03_image_name.jpg, ... wich names I read with a PHP script. Then I loop loading each image and waiting until all are loaded to display them
1. The PHP script reads file names and returns a string with names separated by a "|" char, then I use the split method to store them in imagesNames array and sort it
2. I loop trough imagesNames array loading images
3. Anytime a new image arrives I push it in imagesContainer array and check if all images are loaded to show them
The problem is there's no guarantee they arrive in the same order they were requested. So, how I sort the imagesContainer array by file name, i.e. in the same order they are in imagesNames array?
Thanks in advance

if you know when a new image arrives and you can retrieve that new image file name ...
Well, that's precisely my doubt, how can I know the file name? Is there a property/method for it?
function loadImages() {
for (var i:int=0; i<imagesNames.length; i++) {
var imgLoader:Loader=new Loader;
imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,imgLoaded);
imgLoader.load(new URLRequest(imgPath + imagesNames[i]));
function imgLoaded(par:Event):void {
trace(par.target,par.target.content,par.target.content.name);
Output window:
[object LoaderInfo] [object Bitmap] instance160
[object LoaderInfo] [object Bitmap] instance159
[object LoaderInfo] [object Bitmap] instance161

Is it possible to know the %TEMP% environment variable from my program?

I would like to know if my program want to save a file to the temp storage on my PC, how can I know the %TEMP% environment variable in Windows in my program?

You could pass in the %TEMP% as a system variable at startup. java -cp . -Dwhateveryouwanttocallit=/tmp.
Here's my guess as to what the .bat file might contain. I assume you are running on Windows(TM).
java -cp . -Dwhateveryouwanttocallit=%TEMP%
You could use a batch script to populate the variable and then start up your program. Then you could access the variable by using an extremely rude class called System. You can use System.getProperty("whateveryouwanttocallit") to retrieve the value.

Anyone knows the maximum amount of simultaneous file connection (for the same file) for:

a) READ
and
b) READ / WRITE for both SERVER2008R2 A N D SERVER 2012 ?
Thanks

I belive you should look for any limitations in current tcp connections, and not specificly for the file service it self.
I think you will reach the capacity of what the storage can provide, which most likely will result in read/write timeouts, before you reach the maximum number of current tcp connections.

Is it possible to change the wait time for when you enter an incorrect password on your iphone/ipad?

I reaaally hate how anti-procrastination apps like ColdTurkey don't work for apple products, because what's the point of restricting internet usage on the computer when you can just access it from your apple device? There's no point in using the parental controls or setting passwords for obvious reasons, either.
So I had an idea: from what I know, after guessing the password incorrectly 6 times, the device is locked for 1 min, 7 times, 5 min etc. So I was thinking, is it possible to change the settings, for example, to lock the phone for 60min after 3 wrong password attempts? This would be incredibly helpful!!
(if you know a way but don't want to post it here, please email me instead!)

Thanks a lot Rob. That works.

How to know the printprogram and output type for perticular standard script

how to know the print program and output type for perticular standard script and wt the proceure we will fallow to modifie the standard script..if possible u have any sample code plz share with me.....

Hi Phani,
To know the print program and output type for a standard script we have a table called TNAPR. So just you go to SE11 and provide the table name as TNAPR and choose display option.Then go with display entries option and in selection screen you have to provide the form name for whic you want to know the print program and output type.
To modify a standard script first of all you have to copy the standard form for which you need modifications into Zform. Once you done this you can modify the layout set as per your requirement.Then what ever the modifications you have done in layout set for that you need to populate the data.For this you also need to do some modifications to the print program.so you have to options like directly you can modify the print program as per your requirement and other one is you can create a subroutine and do coding in that subroutine. Then you need call this subroutine in the Script Form.like this you can do modifications to the standard script........................... Reward me if its helpful..........
Thanks & Regards.

Is it possible to read the description of videos that you can see in iTunes on your iPod Touch 4th Gen or 5th Gen?

I was wondering if it's at all possible to read the description of videos that you have on your iPod Touch 4th or 5th Generation. It's available on iTunes, but I was wondering if there was a way to see it on your actual device.
Any answer would be a great help! Thanks

You can omit the title altogether in the URL (together with the succeeding slash, of course). For example, my own podcast URL in the Store is
https://itunes.apple.com/gb/podcast/the-sound-of-78s/id166389425?mt=2
but this works perfectly well:
https://itunes.apple.com/podcast/id166389425
Indeed you can even put your own title:
https://itunes.apple.com/podcast/any_old_title/id166389425
So it's as simple as that!

Is it possible to see the Drill down output in the expanded format by default in SSRS reports?

Hi Guys,
I have created a drill down report. If i preview my report , by default i can see the out put in the aggregated level and i have to drill it to down levels if i want. My requirement is i want to see the data in the leaf level by default means report
should be displayed in the expanded format to the leaf level, if i want i can drill up the report later.
Is this possible in SSRS? Can some one help me out on this?
Thanks in advance.
Regards,
kiran

Hi ,
Thanks for the reply. but if i follow this steps i can see the output in the expanded format but + and - symbols will be interchanged. That means if i drill up i have (-) before the column name and if i drill down it will be (+).
For this to work you need to set properties initial appearance of toggle image
see this example
