Below is the chart of the 10 possible configurations to choose from. Genie 2 will choose a default configuration for you based on your hearing loss. But you don’t necessarily need to stick to that configuration. Experiment with different ones to see which one you like best, and which one gives you the most differentiation between the “s” and the “sh”.
Your loss starts nosediving at 2 KHz. So this is probably the best destination region for you in Speech Rescue. However, this configuration #1 has a lower source region of between 4-7 KHz only. But you can’t really pick and choose much if your hearing loss limits where the ideal destination region is for you. But you can try out between configuration 1 up to 5 maybe and see if you prefer one over another or not.
I’ve played around with several configurations myself, and for my particular hearing loss, I keep going back to configuration 1 as my most preferred choice.
Beside choosing the configuration you like the best, you can also choose to keep the sounds in the source region (higher frequency bands) intact, or remove it. Keeping it intact will let you hear both the original sounds and the lowered sounds.
Then you can also adjust the volume of the lowered sounds that is mixed in with the overall sounds to achieve the most optimum balance of the 2 volumes for you.
Note that whatever your choose in Speech Rescue parameters, it applies the same way to all programs you have with Speech Rescue enabled. By that I mean that you can’t individualize Speech Rescue parameters for each program separately.
