How are your ears doing?

What ist the Frequency Response?

The frequency response specifies the lowest and highest frequency that the acoustic transducer can reproduce. These limits are always set at the point where there is a 3 dB drop (on the lower and upper frequency limit). Unfortunately, this is not standardized, so it is often the case that some manufacturers ?cheat? a bit. Whether headphones really have a frequency response of 20 to 20,000 Hz, for example, remains an open question. The question of what the curve of the frequency response looks like also remains open. Is it linear, or does it go up and down? You would be able to see this on the frequency response curve, but it is rarely included, since it looks pretty ?horrible? for most headphones.

lol, I am 33 year old, and I can hear all of them up to 22kHz !

B/W: I am not music lover ....

Most humans cannot hear past 20! At your age that would put your hearing at superhuman levels! Sorry, but I seriously doubt that you can hear those higher frequencies!

I'm 53 and can hear 16 clearly and I am almost sensing something at 17, perhaps I am imagining that I can, not sure!

this is like comparing apples to oranges since all are using different speakers etc

All consumer speakers/headphones/earphones should still be able to generate up to ~21KHz with ease.

EDIT: Also, the human ear has difficulty receiving signals above 20KHz so this test is a bit off anyway.

that's what most of the people talking about it in comments !

but I can hear it, either its not true 22kHz or its myth that people can't hear above 20kHz, bcoz, im hearing it, its very low but i heard it !

    • draw.io Desktop 30.2.4 by Razvan Serea draw.io desktop is a downloadable security-first diagramming application that runs on Windows, MacOS and Linux. Creating diagrams in the desktop app doesn’t need an internet connection. This is useful when you are disconnected or when you must create diagrams in a highly secure environment, where data protection is of the utmost importance. When you use the draw.io desktop app, your diagrams will be stored on your local device. Because this is a stand-alone application, also designed to run offline, there are no interfaces to cloud storage platforms available. Of course, you can still store your diagrams in folders that are synchronised to your cloud storage if you wish. Easy-to-use diagram editor The draw.io apps work just like the office and drawing tools you are used to using. Drag and drop shapes from the shape libraries and drag to draw connectors between them. Drag connectors to add waypoints and set a precise shape and position, or let them reroute automatically. Double click and start typing to add a label to anything. Create tables and swimlane flows with a familiar tool. Style shapes and connectors with customisable palettes, sketch options, fonts and text formatting tools. Search for shapes, including in open-source icon libraries. Use our vast libraries of shapes and templates, organised into logical categories, to create a range of diagrams and infographics. Generate diagrams from text descriptions using our smart templates. Diagram faster with keyboard shortcuts. draw.io Desktop 30.2.4 changelog: Uses electron 42.4.1 Updates to draw.io core 30.2.4.

    • Microsoft will soon allow some users to block Copilot from analyzing their Office files by Usama Jawad Microsoft Purview is a pretty useful data governance, security, and management service that allows customers to gain enhanced visibility and control over their content. It's meant for commercial customers, such as organizations that are storing data at scale. As AI continues to expand and infiltrate every corner of a firm, many are a bit conscious about the technology gaining access to their confidential data. Microsoft is now making a configuration change that will allow such customers to rest easy. Right now, users within an organization have the option to apply Purview sensitivity labels (when available) to secure certain files and label them as such. For example, if you apply the "Confidential" label on an Excel file, the file will be encrypted, and a "confidential" watermark will be applied to it. So, if this file is shared with anyone, they are aware that its access is supposed to be restricted. Up until now, Microsoft was allowing some connected experiences, like its AI services, to analyze files, regardless of their sensitivity label. This is of major concern to most organizations, as a recent example highlighted how confidential emails with data loss prevention (DLP) policies like privacy labels were being uploaded to Copilot for analysis. As such, Microsoft is updating an existing Purview data label sensitivity setting that prevents "some connected experiences that analyze content", from being blocked completely from doing this. The label isn't changing, but the blocking is now being enforced across all connected services (including Copilot and other AI tools), and now extends to Microsoft Word, Excel, and PowerPoint. Files with the label applied already will get this enhancement automatically too once it becomes available. Microsoft has urged IT admins to inform their respective helpdesk and compliance teams, update internal documentation, and review sensitivity labels to ensure that they meet their respective compliance needs. This change is tagged as MC1297982 in the Message Center. General availability is scheduled to begin in a phased manner soon and will complete by the end of next month. That said, it is important to note that this only applies to commercial customers who have a license that allows them to use Purview.
