THE INSTITUTEAbout 30 percent of women who have had breast cancer surgery experience post-mastectomy pain syndrome, nerve pain that occurs in the chest wall or armpit, according to the American Cancer Society (ACS).

The National Cancer Institute reports that opioids or other pain medications often are prescribed to combat the condition but that many patients cannot afford the pills, which can cost up to US $12,000 per year, or they are too afraid of becoming addicted. Also, the ACS has found that such medicines don’t always work well for nerve pain.

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
