“RELATIVE HUMIDITY” —>
-the ratio of how much water vapour is in the air to how much water vapour the air could potentially contain at a given [temperature / pressure]-
.
Guitar humidifiers maintain 45% to 50% relative humidity to prevent the wood from being damaged by being too dry or too moist, which can cause it to crack, warp, or swell.
This specific range is the accepted sweet spot that prevents the wood from shrinking and cracking in dry conditions, while also avoiding the problems associated with excess moisture, such as swelling and the potential for mold, as described by Electric Herald (https://www.electricherald.com/guitar-players-guide-to-moisture-and-humidity/)
Why this specific range is important
- Prevents shrinking and cracking: When air is too dry (especially in winter due to heating), the wood loses moisture and shrinks, which can lead to hairline cracks, particularly in the soundboard, and the edges of the frets can become sharp.
- Prevents swelling and warping: If the guitar is exposed to too much moisture, the wood will absorb it and expand. This can cause warping of the neck or body, seam separations, and other damage.
- Maintains sound and playability: Maintaining a consistent humidity level helps preserve the instrument’s tone and action. In dry conditions, a guitar can become dull-sounding and have a higher action, while in humid conditions, the tone can be negatively affected.
- Protects the instrument: This humidity range is considered optimal because it balances the moisture content in the wood, preventing the stress that comes with rapid expansion and contraction, which ultimately extends the instrument’s lifespan and maintains its structural integrity.
