Emergency and critical care areas often face many sound disturbances. Background noise in emergency rooms (ERs) and intensive care units (ICUs) can make it difficult to hear body sounds clearly. Accurate auscultation in such noisy settings is needed to make fast and correct decisions. The Knya 6sense Stethoscope is built with Active Noise Cancellation (ANC) technology to support this. ANC helps reduce unwanted noise so that the required body sounds become clearer. This blog discusses how the Knya 6sense Stethoscope works in real-world situations, especially in noisy hospital environments.

Understanding Active Noise Cancellation in Stethoscopes
Active Noise Cancellation is a method used to remove outside noise by producing opposite sound waves. In medical tools like the Knya 6sense Stethoscope, this method helps focus on body sounds such as heartbeats, breath sounds, and bowel sounds. This can be helpful in busy areas with continuous sound disturbances. ANC does not only lower noise but allows better clarity in listening, which can improve detection and diagnosis.
Why ER and ICU Settings Need ANC
ERs and ICUs are filled with machines, alarms, and talking staff. These sounds can interfere with auscultation. A stethoscope with ANC can support medical staff in listening to patients without delay or mistake. Fast listening in these areas helps save time and can lead to quicker action. The Knya 6sense Stethoscope provides this advantage with its built-in ANC system.
Case Study 1: Emergency Room – Chest Pain Evaluation
In a busy ER, a middle-aged patient was brought in with chest pain. The surroundings had noise from monitors, stretchers, and other patients. Using a traditional stethoscope made it hard to hear any heart murmurs. A switch to the Knya 6sense Stethoscope allowed clear hearing of a faint murmur that pointed to valve trouble. ANC removed the extra background noise and made the murmur easy to catch. This led to early diagnosis and faster imaging tests.
Case Study 2: ICU – Respiratory Monitoring
A patient on a ventilator in the ICU needed close lung sound monitoring. Mechanical ventilation and surrounding alarms made hearing breath sounds very difficult. With the use of the Knya 6sense Stethoscope, lung auscultation was possible even when noise was high. A faint wheeze was heard, and this sign helped guide the next step of bronchodilator treatment. The ANC feature allowed the care team to hear breath sounds that could otherwise go unnoticed.
Case Study 3: Pediatric ER – Crying Infants and Lung Sounds
In a pediatric ER, a newborn with suspected pneumonia arrived while many infants were crying nearby. It became tough to hear fine crackles using a normal stethoscope. The ANC in the Knya 6sense Stethoscope helped cancel the crying sounds and revealed small crackles in the lower lung zones. This led to early antibiotic use and timely admission to the neonatal unit.
Case Study 4: Trauma ICU – Abdominal Assessment
A trauma patient was admitted with blunt injury to the stomach. Bowel sounds were not clearly heard due to beeping monitors and team communication in the ICU. The Knya 6sense Stethoscope helped detect absence of bowel sounds clearly using ANC. This supported the suspicion of internal injury, leading to immediate imaging and surgery.
Case Study 5: Cardiac ICU – Murmur Evaluation
A patient in a cardiac ICU needed murmur grading before planning a surgery. Normal auscultation was affected by the continuous hum of cardiac monitors. The Knya 6sense Stethoscope made murmur detection and grading easier by lowering the monitor noise using ANC. This gave the cardiac team better data before finalizing surgery plans.
Case Study 6: ER – COVID-19 Ward Auscultation
During a peak COVID-19 wave, an ER room had multiple patients on oxygen. The sound of oxygen delivery systems made auscultation of lungs difficult. A patient with sudden breathing difficulty needed fast lung evaluation. The Knya 6sense Stethoscope filtered the oxygen flow noise and allowed recognition of basal crepitations. This led to oxygen support adjustment and steroid treatment.
Case Study 7: ICU – Multi-Patient Monitoring
In an ICU room with many patients, a junior resident was asked to auscultate all patients in a short time. Using a regular stethoscope delayed the task as repeated listening was needed. Switching to the Knya 6sense Stethoscope reduced repeat checking. The ANC feature gave quicker clarity on breath and bowel sounds, saving time and improving reporting.
Case Study 8: Pre-Hospital Emergency Care
During ambulance care, noise from sirens and road traffic disturbs auscultation. A paramedic attending to a road accident victim used the Knya 6sense Stethoscope to check breath sounds while en route. ANC cancelled the background siren and allowed the detection of unequal breath sounds, leading to the decision for early chest tube placement on hospital arrival.

How Knya 6sense ANC Technology Works?
The Knya 6sense Stethoscope uses built-in microphones to pick up outside noise. Then, it creates opposite sound waves to cancel the noise. This is done in real time. The result is clearer, uninterrupted body sound output. The stethoscope is easy to use and does not need many settings to start ANC. It can be used in both high-noise and regular settings.
Advantages in Clinical Work
-
Reduces mishearing due to external noise
-
Saves time by avoiding repeated auscultation
-
Supports junior staff and students in learning better
-
Helps in early detection of sounds such as murmurs, wheezing, crackles
-
Useful in mobile medical units, ambulances, emergency tents
Device Handling and Cleaning
The Knya 6sense Stethoscope is designed for daily use. The ANC system works without affecting cleaning methods. The device can be wiped and stored like regular stethoscopes. It is light, easy to carry, and suited for fast-paced work.
Clinical Feedback and Reports
Doctors using the Knya 6sense Stethoscope in ER and ICU have reported better clarity, especially in lung and heart sound detection. Many have shared feedback about reduced listening fatigue and more confidence in noisy areas. Resident doctors and interns found auscultation less confusing while learning.
Education Use
In teaching hospitals, ANC can help learners focus better. When the teaching doctor and student both use ANC-based stethoscopes, they can compare sounds more accurately. Knya 6sense allows sound amplification, which also helps when explaining findings in class or bedside teaching.

Conclusion
Accurate auscultation in noisy hospital areas remains a challenge. Active Noise Cancellation technology offers a direct solution by reducing surrounding sounds. The Knya 6sense Stethoscope applies this method to real clinical environments. ERs, ICUs, and ambulance settings all benefit from faster and clearer sound detection. Multiple case examples show that the use of ANC can help improve speed and accuracy in patient care. The Knya 6sense Stethoscope provides a modern tool for better sound listening in difficult areas. It continues to be adopted by doctors, paramedics, and students who face loud settings daily.
