Syllabic vs Dual compression

I am trialing Costco’s KS8 aids which are rebranded Rexton/Signia aids. I found this document from Sivantos/Siemens which talks about compression and, although its old (2006), seems to be relevant to my aids.

https://media.sivantos.com/siemens-website/media/2014/07/2006_understanding-compression.pdf110

Under the section on attack and release times it states the following:

Short release times are generally 150 msec or less
ƒ Also known as syllabic compression

And later in the section Adaptive attack and release times

Siemens use adaptive compression: choice of “syllabic” or “dual”
compression

In the Connexx 8 software I noticed that you can choose between syllabic or dual under fine tuning, parameters tab. The default is syllabic.

Can anyone with more knowledge than me comment on the differences between the two? Is syllabic better for speech and dual more natural sounding? Or am I way off base here?

I’m thinking of changing the setting in my music program to see if I can tell the difference

Old thread, but I basically have the same question as John. I have noticed that v5 defaults to use syllabic compression. On the other hand defaults to dual compression. My read of this is that syllabic is faster than dual. Is this correct?

Second question would be the “adaptive” part. I gather that modern aids adapt the attack and release times. Does that mean that both syllabic and dual compression both use adaptive times?
