  • A new modernized look, with a range of colors and updated fonts and layout
  • A new Signals in Noise section – a technical article where NHCA experts separate the research from the noise
  • A new Tone Bursts section – a short burst of knowledge from our NHCA experts
  • And more great content!

Spectrum will continue to improve over time to benefit our members. Don’t miss an issue!
