Pursuing High-Intelligibility Audio for Medical Diagnostic Precision

Audio clarity in medical diagnostics and surgery has a direct impact on clinical outcomes. Subtle acoustic details can make the difference between accurate diagnoses and missed conditions.

We previously explored clear audio for healthcare devices. This article shows how MISCO provides loudspeakers and audio expertise for medical diagnostic and surgical equipment.

High-Intelligibility Audio for Diagnostic Precision

To ensure precise clinical assessments, medical providers must accurately identify subtle acoustic differences detected by ultrasound systems or cardiac monitoring devices. Those sounds are often similar, with only subtle frequency differences (such as various cardiac murmurs or lung sounds). Hearing those sounds—clearly, without distortion—helps with better analysis and diagnosis.

Hospital environments also contain numerous competing sound sources that can mask critical diagnostic audio cues. Diagnostic equipment must transmit the full spectrum of medically significant sounds without losing critical details.

Engineering Solutions for Diagnostic Clarity

MISCO's approach to loudspeakers for diagnostic equipment prioritizes intelligibility through specialized engineering:

• Frequency response optimization: We tune speakers to emphasize the frequency ranges most critical for diagnostic interpretation.
• Customized enclosure design: We develop audio enclosures that minimize phase distortion and optimize sound propagation for diagnostic environments.
• Signal processing integration: Our systems integrate seamlessly with digital signal processing to enhance clarity in noisy clinical settings.

For example, we partnered with an ultrasound system company to develop a system audio module for their diagnostic equipment. Intelligibility was the primary requirement. We created a compact speaker system that reproduced subtle diagnostic sounds with exceptional clarity within strict space constraints. The result: improved physician ability to hear subtle diagnostic sounds, enhancing clinical assessment accuracy without requiring additional equipment space. We then went one step further, using the audio module to split the video and audio signals from the ultrasound transducer. This one audio module accomplishes two functions.

Audio Solutions for Surgical Innovation

Modern surgical environments increasingly involve remote procedures, robotic assistance, and distributed teams, all requiring exceptional audio clarity for effective communication and coordination. System failure is not an option in life-critical procedures like surgery. Audio must reach surgical staff without distracting echoes or reflections, components must withstand rigorous sterilization, and sound must maintain clarity across distributed systems for telesurgery.

We are working with medical technology companies to develop two-way communication systems, connecting doctors performing surgery, medical staff present in the surgery room, and observers. In one example, we place our speakers into an enclosure, and then place that enclosure into another customer-provided enclosure that will contain the microphones.

These systems maintain crucial communication clarity in remote surgical settings, where every word and instruction must be perfectly understood.

Engineering Services and Design Collaboration

MISCO supports the medical industry through comprehensive engineering services. 

• Our audio experts identify the most suitable speakers and medical audio systems for your project. 
• Our deep understanding of medical audio applications allows us to advise on the best components and collaborate to design complete audio systems that fulfill your project requirements. 
• Our engineering capabilities allow us to design and manufacture enclosures that blend seamlessly (or integrate cosmetically) with the end product.

U.S.-Based Manufacturing: A Critical Advantage

MISCO's U.S.-based manufacturing provides medical device manufacturers with a significant strategic advantage. Our U.S. capabilities allowed us to quickly scale production for ventilator alarm speakers during the COVID-19 pandemic. At a time of critical shortages of ventilators, MISCO was the only company able to build a speaker for a ventilator in the U.S.

We maintain stringent quality control during accelerated production, provide regulatory documentation without international shipping delays, and offer shortened lead times when every day matters for patient care. These advantages translate to faster development cycles, more reliable production scheduling, and ultimately, better support for critical healthcare applications.
