Digital stethoscopes are computer aided products which can read sound, vibration, or acoustic signals. Digital stethoscopes can store sound and this sound can be played again and again. The stored sound can be send to another colleague in case you want his opinion. Digital stethoscopes are often used by veterinarians.
There are different types of digital stethoscopes such as the DRG Echo amplified digital stethoscope, Littmann electronic stethoscope, and web based remote digital stethoscope.
A DRG Echo amplified digital stethoscope can switch easily between three modes of operation such as digital, diaphragm and bell. The digital mode boasts 400% increase in amplification over traditional stethoscopes. Its signal processing technology assists in filtering electronic noise. The headset has been configured for ease-of-use and the external noise reduction tube technology significantly reduces the amount of external noise heard through the stethoscope, while its stainless steel coils optimize internal acoustics. This digital stethoscope can replay sounds at regular and slow speeds.
The Littmann electronic stethoscope also has three frequency response modes such as bell, diaphragm, and external range. It has an anatomically correct headset and the features of amplification and proprietary ambient noise reduction technology. This helps to reduce noise without eliminating critical body sounds. Moreover, its digital signal processing offers recording, storage and playback capabilities. It has the ability to transfer recorded sounds through an infrared transmission to another model or hand held device.
A web-based remote digital stethoscope integrates current software, hardware interface devices, PC and Internet into the remotely operated virtual instrumentation. Digital remote stethoscope can also be easily connected to LAN and WAN. DRG Echo plus with data link is also used as a digital stethoscope. It has the ability to download the recorded patient data.
