This sound effect can be found on the Series 2000 Sound Effects Library, which was made by Sound Ideas. It was later reused in HOSPITAL - INTENSIVE CARE ROOM: HEART MONITOR, VENTILATOR, E. E. G. AMBIENCE, which is available on the Series 7000 Ambience II Sound Effects Library (also made by Sound Ideas).
The Angelsounds JPD-100S Pocket Fetal Doppler is a portable fetal doppler that allows a mother-to-be to listen to their unborn child's first heartbeats. This battery-operated device is suitable for prenatal heartbeat monitoring from the comfort and privacy of one's own home. Using this home doppler does not require the application of ultrasound gel to detect fetal heartbeat sounds, reducing cost and maintenance when regularly using the JPD-100S.
The heartbeat monitor's audio signal has adjustable volume and digital output for compatibility with external headphones, providing simple auscultation with higher clarity when listening. With the headphone jack and included recording cable, users can link the monitor to a recording device for saving a baby's heartbeat recording to CD, MP3, a PC, a cell phone, or another storage medium of their choice to share the happiness with their friends and family members.
This genuine Angelsounds Fetal Doppler Baby Heart Rate Monitor is the perfect way to listen to your baby's heartbeat right at home. Now all mothers can enjoy the pleasure of listening to their baby's heart right in the comfort of their own home.
Many expectant mothers worry about their unborn babies during pregnancy, and it can be reassuring to buy a fetal doppler system. This popular Angelsounds fetal doppler model includes the necessary items to begin listening to heartbeat sounds and comes factory-direct from BestMedicalDirect.
A Fetal Doppler is a device used to monitor a baby's heart rate throughout pregnancy. The device is non-invasive, which makes it a good safety choice for all pregnant mothers. The heart rate is measured using the doppler effect, emitting and receiving ultrasonic sound waves to monitor shifts in the pitch of the sound waves. As every returning sound wave is measured, the speakers on the heart monitor output the heartbeat sounds.
An embryo's heart begins beating around 22 days after conception, but it takes much longer for doctors and parents to be able to listen to the heartbeat. Between the 9th to 12th weeks of pregnancy, most fetal dopplers can pick up heartbeat sounds and tones. Some heartbeats may be hard to find, and this is perfectly normal. Just be patient and try more areas around the belly, then eventually, you will hear it!
The Angelsounds Fetal Doppler is simple to use. The mother (or father) begins by pressing the device probe against the abdomen, puts on the headphones, and turns it on to hear the baby's heart beating. It comes equipped with headphones and a recording cable so that mothers can record the baby's heartbeat to a computer.
To record the baby's heartbeat, mothers can plug the recording cable into either of the headphone sockets on the doppler. The opposite cable end then plugs into the microphone socket on a computer. Mothers can plug headphones into the other socket to listen to the heartbeat while recording. Press the doppler probe against the abdomen and turn on the Angelsounds device. Using recording software on the computer, press the "Record" button, and the computer will begin recording the baby's heartbeat.
For users of Windows XP and Win7: You can use a sound recorder in the Windows OS to record your baby's heartbeat. Click Start, select programs, go to accessory, then select entertainment, and you will see the Sound Recorder application.
Can this Doppler heart rate monitor be used on any heart?
Yes. Of course, the primary function of this doppler heart rate monitor is to be able to listen to a baby's heartbeat, but users can still use it to listen to the heart of a child or adult as well.
Throughout the song, there are hospital heart failure monitor sound effects that randomly appear in the song. Basically, it represents the friendship failing and having its ups and downs, just like the irregularity of the heartbeat in the monitor sound effect. And then, at the very end of the song, there is a long beep, which is a hospital heart failure monitor sound effect where the patient is completely dead and it basically represents the friendship being completely dead.
Constant (carrier signal) LFV is a traditionally used type of low-frequency stimulation, while amplitude modulation of LFV, with different durations, has not yet been sufficiently studied. In the case of both types of LFV, the same frequency of 40 Hz, comparable strength of low-frequency waves and the same type of recording of natural sounds (river sounds in forest) were used. Concerning the amplitude modulation, three types of amplitude modulation (AM) 40 Hz signal with different cycle lengths and then 5 min pure unmodulated 40 Hz signal (carrier signal), provided a total length of stimulation of 20 min. The contrasting effect of the sequentially dosed series was then considered and involved gradually shortening the cycle length (14 s, 10 s, 6 s = from long to short) to the original shape of the 40 Hz carrier signal. Each AM cycle was supplemented by silence at the same length as the length of one modulation signal cycle (stimulus processing time and organism response):
In this study, HRV frequency indices were used as the primary physiological outcome. HRV analysis provides a non-invasive method for evaluating cardiac autonomic regulation [25]. To calculate HRV frequency indices, the electrocardiogram was recorded using a Polar V800 heart rate monitor (Polar, Kempele, Finland), which has been proved to be a valid device [26]. RR intervals, which were defined as the duration between two adjacent heartbeats, or, more precisely, as the duration between R waves on the electrocardiogram, were measured with a resolution of 1 ms. HRV was analyzed before and after the interventions by means of orthoclinostatic maneuver (Figure 3). The orthoclinostatic maneuver lasted 12 min and consisted of 5 min standing and 7 min in a supine position (with a 1 min stabilization period) [27]. HRV was also continuously analyzed during the intervention lasting 20 min [28]. The RR intervals were visually examined by an expert, and all artifacts were manually filtered. From the orthoclinostatic maneuver, two 5-min segments (standing, supine) were extracted. From the recording taken during the intervention, four adjacent 5 min segments were extracted. HRV frequency indices were calculated using a special application DiANS PF8 (DIMEA Group, Olomouc, Czech Republic) from measured RR intervals. The calculations were based on spectral analysis performed using Fast Fourier Transform with a sliding 256 points Hanning window. The power spectra were quantified by integrating the area under the power spectral density curve. Two frequency bands were used: low frequency (LF) from 0.05 to 0.15 Hz, and high frequency (HF) from 0.15 to 0.50 Hz. The HF power was solely modulated by cardiac vagal activity, while the LF power was associated with baroreflex and sympathetic activity on the sinus node, and the LF/HF ratio reflected sympathovagal balance [21]. The respiration activity was not monitored.
