Good question. And obviously the measure for sound decibel actually works this way. Humans hear the power of sound logarithmically, yes, the dB scale reflects the way we perceive audio intensity.
So it's interesting that the fine controls of most volume controls are up in the "high volume" area and not either evenly-spaced or logarithmic.
By logarithmic scale, do you mean in visually in the volume control interface? AlanGeorge No. Was discussed here: electronics. Show 2 more comments. Active Oldest Votes. Improve this answer.

And if they're not then often there is a hidden graduation at either the pixel level, or it's just physically not possible to adjust a physical control with such high precision. The question is why is the precision all at high volume, and no precision found at low volume.
A harsh guess would be that it's just not financially worth it. Other than that I can't think of any reason. Andrew Martin Andrew Martin Not financially worth it? This behavior may cause Windows Explorer or the dir command to display inaccurate file and folder totals and size statistics.
To include these types of files in the overall statistics, change Folder Options. In the Backup Utility, click the Backup tab, and then select the check box for the whole volume that is affected for example: D: , and then click Start Backup. After the backup is complete, open the backup report and compare folder for folder the NTBackup log output with the d-dir.
Because backup can access all the files, its report may contain folders and files that Windows Explorer and the dir command do not display. You may find it easier to use the NTBackup interface to locate the volume without backing up the volume when you want to search for large files or folders that you cannot access by using Windows Explorer.
After you locate the files that you do not have access to, you can add or change permissions by using the Security tab while you view the properties of the file or folder in Windows Explorer. By default, you cannot access the System Volume Information folder. You may notice folders or files that do not have a Security tab. Or, you may not be able to re-assign permissions to the affected folders and files.
You may receive the following error message when you try to access them:. If you have any such folders, contact Microsoft Product Support Services for additional help. Folders or files that contain invalid or reserved file names may also be excluded from file and folder statistics. Folders or files that contain leading or trailing spaces are valid in NTFS, but they are not valid from a Win32 subsystem point of view.
Therefore, neither Windows Explorer nor a command prompt can reliably work with them. You may not be able to rename or delete these files or folders. When you try to do so, you may receive one of the following error messages:.
If you have folders or files that you cannot delete or rename, contact Microsoft Product Support Services. It is small when it is created approximately 16 KB , but it grows as files and folders are created on the volume. As files are added to the volume, the MFT grows. That is why you do not regain the space used by the MFT after you delete a large number of files,. To see exactly how large the MFT is, you can use the built-in defragmenter to analyze the volume.
The resulting report provides detailed information about the size and number of fragments in the MFT. However, for more complete information about how much space overhead the whole NTFS is using, run the chkdsk. NTFS permits files and folders to contain alternate data streams. With this feature, you can associate multiple data allocations with a single file or folder.
Below is the function I use for calculating the audio DB level. What am I doing wrong here? Thank you in advance! Max - Volume. Improve this question. Add a comment. Active Oldest Votes. Improve this answer. Thank you for this answer. As soon as I tried it out I will give you feedback and accept the answer. Hello again.
I tried it out. Unfortunately it's not the solution I need. This is a linear volume slider and not a logarithmic. I'm glad you found your answer. Thats right but your answer was a linear function if I am right.
I found the solution. Here's the current code sample I am using in case someone will need it in the future.
