Listening to various lung sounds has proven to be an important diagnostic tool for detecting and monitoring certain types of lung diseases. In this study a computer-based system has been designed for easy measurement and analysis of lung sound using the software package DasyLAB. The designed system presents the following features: it is able to digitally record the lung sounds which are captured with an electronic stethoscope plugged to a sound card on a portable computer, display the lung sound waveform for auscultation sites, record the lung sound into the ASCII format, acoustically reproduce the lung sound, edit and print the sound waveforms, display its time-expanded waveform, compute the Fast Fourier Transform (FFT), and display the power spectrum and spectrogram.
Changing or disabling sounds using the instructions below only affects sounds relating to Windows functionality. Software and game sounds are controlled through the program itself and are not affected by changing or disabling Windows event sounds.

Audio ports are exposed to elements that may cause a build-up of dust or even physical damage. Audio performance issues may occur if there is any damage that is caused to the audio cables or the audio ports on the computer.
Most desktop computers come with 3 or more audio connectors. Most laptops come with one combo connector that supports both headphones and a microphone. Verify that the speaker or soundbar cables are connected properly from the device to the computer. Audio connectors and plugs on the sound card are color-coded on desktops to help with a proper connection (Figure 1).
The default audio playback device is Microsoft Windows's device to output (play) sound. You can select which device to use by default when connecting speakers, soundbar, earphones or headphones, Bluetooth headset, or other audio devices to the computer. Windows can play audio through the speaker or line-out port, Bluetooth, HDMI, DisplayPort (DP), or USB-C Thunderbolt 3 ports. Selecting the correct playback device and checking the volume settings for audio playback to work on the computer is essential.
Microsoft Windows includes various troubleshooters that are designed to quickly diagnose and automatically resolve many personal computer problems. Although Windows Troubleshooter cannot fix hardware problems, they are a great place to start if you encounter a problem with the computer. Windows Troubleshooters are built into the Control Panel in Windows 11, Windows 10, Windows 8.1, or Windows 8.
Dell Technologies recommends updating the device drivers and BIOS as part of your scheduled update cycle. Device drivers and BIOS updates may contain feature enhancements or changes that help keep your system software current and compatible with other computer modules (hardware and software) as well as increased stability.
Running a hardware diagnostic test can help you identify hardware-related problems and provide you with troubleshooting steps to help resolve the issue. To determine if your Dell computer is experiencing a hardware problem, it is recommended that you first run a hardware diagnostic test. Dell offers both integrated and online diagnostics.
System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore should be used before restoring the computer to factory default settings.
If the diagnostic tests on the audio or sound card passed, it is most definitely an issue that is related to software installed on the computer. If the above troubleshooting steps did not resolve the issue, you can try to restore the computer to factory default settings as a last resort.
Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore the computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before beginning this process.
Pneumothorax is usually diagnosed based on the attenuation of respiratory sounds of the affected side on auscultation, but it requires a skilled technique and is limited to subjective evaluation. Thus, we designed a device which analyzes and converts the frequency of auscultatory sounds to numerical values with a computer. With this device, the bilateral sound pressure levels were compared between groups of 25 healthy subjects and 21 patients with pneumothorax to investigate the efficacy of the diagnosing tool of pneumothorax. While recording respiratory sounds of the bilateral precordial regions, the fast Fourier transform was applied with a frequency analysis software, power spectra of the auscultatory sounds were displayed in real-time, and the sound pressure level was compared between the bilateral sides. The difference was investigated at frequencies judged as less likely to be influenced by cardiac sounds (200-400 Hz). No difference was observed in the control group (n = 25, P > 0.05), but respiratory sound attenuation was detectable on the affected side in the pneumothorax group (n = 21, P
A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Typical uses of sound cards or sound card functionality include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection. Sound cards are also used for computer-based communication such as voice over IP and teleconferencing.
An important sound card characteristic is polyphony, which refers to its ability to process and output multiple independent voices or sounds simultaneously. These distinct channels are seen as the number of audio outputs, which may correspond to a speaker configuration such as 2.0 (stereo), 2.1 (stereo and sub woofer), 5.1 (surround), or other configurations. Sometimes, the terms voice and channel are used interchangeably to indicate the degree of polyphony, not the output speaker configuration. For example, much older sound chips could accommodate three voices, but only one output audio channel (i.e., a single mono output), requiring all voices to be mixed together. Later cards, such as the AdLib sound card, had a 9-voice polyphony combined in 1 mono output channel.
Sound cards for IBM PC compatible computers were very uncommon until 1988. For the majority IBM PC users, the internal PC speaker was the only way for early PC software to produce sound and music.[4] The speaker hardware was typically limited to square waves. The resulting sound was generally described as "beeps and boops" which resulted in the common nickname beeper. Several companies, most notably Access Software, developed techniques for digital sound reproduction over the PC speaker like RealSound. The resulting audio, while functional, suffered from the heavily distorted output and low volume, and usually required all other processing to be stopped while sounds were played. Other home computers of the 1980s like the Commodore 64 included hardware support for digital sound playback or music synthesis, leaving the IBM PC at a disadvantage when it came to multimedia applications. Early sound cards for the IBM PC platform were not designed for gaming or multimedia applications, but rather on specific audio applications, such as music composition with the AdLib Personal Music System, IBM Music Feature Card, and Creative Music System, or on speech synthesis like Digispeech DS201, Covox Speech Thing, and Street Electronics Echo.
By 1992, one sound card vendor advertised that its product was "Sound Blaster, AdLib, Disney Sound Source and Covox Speech Thing Compatible!"[8] Responding to readers complaining about an article on sound cards that unfavorably mentioned the Gravis Ultrasound, Computer Gaming World stated in January 1994 that, "The de facto standard in the gaming world is Sound Blaster compatibility ... It would have been unfair to have recommended anything else."[9] The magazine that year stated that Wing Commander II was "Probably the game responsible" for making it the standard card.[10] The Sound Blaster line of cards, together with the first inexpensive CD-ROM drives and evolving video technology, ushered in a new era of multimedia computer applications that could play back CD audio, add recorded dialogue to video games, or even reproduce full motion video (albeit at much lower resolutions and quality in early days). The widespread decision to support the Sound Blaster design in multimedia and entertainment titles meant that future sound cards such as Media Vision's Pro Audio Spectrum and the Gravis Ultrasound had to be Sound Blaster compatible if they were to sell well. Until the early 2000s, when the AC'97 audio standard became more widespread and eventually usurped the SoundBlaster as a standard due to its low cost and integration into many motherboards, Sound Blaster compatibility was a standard that many other sound cards supported to maintain compatibility with many games and applications released. 041b061a72
