WebJan 14, 2016 · thedjfx 🎙️. The former (deep) is ambiguous and can mean any ratio or threshold, IMO. Low ratio vs high threshold only means how much (or little) the signal will get compressed versus at what level this compression ratio (the processor) should be triggered. That is, ratio and threshold are two different parameters. Yes, exactly.

Believe it or not, high-compression engines of the late ’60s, with compression ratios up to 12.5:1, had higher thermal efficiencies than many of today’s engines. WebNov 20, 2024 · Step 7 – Determine the compression ratio: Use the formula below to compute the compression ratio. Compression ratio = { (swept volume + clearance volume) / clearance volume} Swept volume = (π) x (bore radius squared) x (exposed cylinder height).
