I’d opine it’s rather difficult to tell why you’re hearing what you’re hearing, Hour to Hour, Day to Day or Week to Week, Rain or Shine. What can I say? I would not (rpt not) be very surprised if the sound is affected by Sunspot and solar flare activity. If you’re interested you can keep a log, correlating SQ to sunspot and solar flare activity or weather, etc. And unless you’re just sitting there watching the graphene cure and not doing anything at all to the system, you cannot separate all the variables. Things are far from static. They’re very dynamic.
Plus there are great big variables that are uh, unmentionable. And I don’t want to get banned so I won’t mention them.

“The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center, which provides important resources to describe the space environment, including geomagnetic storms, solar radiation storms and radio blackouts, is forecasting the possibility of moderate-to-strong geomagnetic activity for Friday and Saturday. The source of the activity is a coronal mass ejection observed earlier this week. Coronal mass ejections (CMEs) – also known as solar flares – create a large mass of charged solar energetic particles that escape from the sun’s corona and travel to the earth.
In situations such as this, an established, well-coordinated strategy is activated. The Energy Department, other government agencies, the North American Electric Reliability Corporation (NERC), and electricity utilities across the U.S. are working together, closely monitoring the situation and evaluating the impact to the Nation’s electric grid. NOAA issued a G3 Geomagnetic Storm Watch last night so that the nation’s power grid operators have plenty of time to take appropriate actions for this level of storm. Reliability Coordinators for the power grid have been notified by NERC per their operating plans. The utility industry is monitoring the situation closely, following the NOAA reports and analyzing data from the Electric Power Research Institute’s (EPRI) Sunburst program, a geomagnetic-induced current monitoring system. The industry is prepared to take action as needed, including reducing load if necessary and changing operational settings to respond to system needs.”
