I used a smartphone app to raise and lower background sound levels.
New England has lower background radiation, Colorado is much higher, yet cancer rates in New England are higher than in Colorado – an inverse effect.
The difficulty can be overcome to some degree by achieving lower background contamination, by improving instrument sensitivity, and by finding minerals with abundant parent isotopes.
More importantly, LMBs have a much lower background noise and allow faster reaction rates.
The higher counting efficiency and lower background made it possible to perform the low-level monitoring.
In addition, the detection system has a lower background signal owing to application of superparamagnetic nanoclusters.
The proposed aptasensor has the advantages of higher sensitivity and lower background current.
Straight from the owner's manual: "Our unique shape and earcup design do provide passive sound isolation with lower background noise".
The obtained dendritic Au/BDD electrode has lower background current, better electrochemical performance and higher capacity to immobilize biomolecules.
Comparison with SPCM and glass beads, SHPCM could provide the more wide dynamic detection linear range and lower background signal.
Furthermore, new ideas for lower background readout devices are studied, in order to avoid the use of PhotoMultiplier Tubes (PMTs).
