Studies Comparing Non-electronic, Cardiology-type Stethoscopes and the 3M™ Littmann® Electronic Stethoscope 3000 Series Had These Findings:

With the Littmann® Model 3000 Series Stethoscope…

83% of cardiologists indicated it was easier to detect/hear a S3 gallop

82% of cardiologists indicated it was easier to detect/hear an aortic regurgitation murmur (Grade 1 or 2)²

90% of critical care nurses indicated it was easier to detect/hear abnormal lung sounds³

When Using a Non-Electronic, Cardiology-Type Stethoscope vs. the Littmann® Model 3000 Series Stethoscope…

Cardiologists missed an S3 gallop 40% MORE OFTEN¹

Cardiologists missed a Grade 2 aortic regurgitation murmur 5 TIMES MORE OFTEN²

Critical care nurses misidentified whether a sound was normal or abnormal TWO TIMES MORE OFTEN³

Don't miss the sounds you need to hear!

In Controlled Experiments:

(2) 100 cardiologists listened to pre-recorded heart sounds with and without a Grade I or Grade 2 aortic regurgitation murmur, presented in random order in the presence of 70 –75 dB ambient noise. They listened with both a Littmann® Model 3000 Series and an acoustic (non-electronic) cardiology-type stethoscope. Download Now (pdf, 84k)

(3) 136 Critical care nurses listened to, and were asked to identify, pre-recorded normal and abnormal lung sounds presented in the presence of 70-75 dB ambient noise, using a Littmann® Model 3000 Series and an acoustic (non-electronic) cardiology-type stethoscope. Download Now (pdf, 84k)

Real Life Observations

Why so many clinicians love the 3M™ Littmann® Electronic Stethoscope Model 3000 Series sound experience

Anesthesiologist
"Helps me pick up subtle, critical changes in breath sounds, even in the noisy operating room and pre-op areas."

Cardiovascular Nurse
"I was able to quickly pick up difficult to hear heart murmurs that my peers with many more years of experience had trouble differentiating using a conventional stethoscope."

"Allows me to easily differentiate between high and low frequency sounds even when alarms and other ambient noise surrounds me."

"Quiets the buzzing and humming of many machines when trying to listen to lung, heart and abdominal sounds."

EMT
"Enables me to hear in the back of a screaming ambulance."

Internist
"Acoustically superb, excellent diagnostic instrument."

Internist
"Offers a marked reduction in unwanted ambient noise when I listen for abnormal heart sounds."

MD - Emergency Medicine
"Helped me discover a carotid bruit that I wasn’t able to hear with my conventional stethoscope."

MD - Pediatrician
"I was immediately impressed with the acoustic clarity of hearing heart tones and murmurs, and the ability to discern penumonias at an earlier treatment stage."

MD - Pediatrics and Family Medicine
"The ambient noise reduction is excellent, especially in a treatment room with two active kids. And breath sounds are much easier to analyze."

Nurse Practitioner
"I can record, then listen, slow it down, identify it, listen in real time, then go back to the individual with the heart sound and listen through the stethoscope."

Nursing Student
"Blocks out virtually all ambient noise and is comfortable too!"

Pediatric Nurse
"I can listen to patients on ventilators in the ICU even while nurses and doctors are talking and alarms are sounding."

Pediatrician
"Makes hearing children's cardiac and respiratory sounds much easier, even with other children running around."

Respiratory Therapist
"Allows me to hear the very faint wheezes and crackles that I couldn't hear with a conventional stethoscope."
