Since I listened to the new Tenth Doctor Adventures alone, I'm getting a second listening with my husband now, and here's my review
I think the thing that hit me the hardest was hearing the series 4 theme music after the opening scene, just like in the TV show. It was really the thing that told me that yes, the Tenth Doctor has returned, and the orchestral version of the theme is just gorgeous. (Okay, yes, I prefer the series 1-3 version, but series 4's is wonderful, too.) Getting into the story was a bit difficult, though. The opening scenes switch back and forth between Jill, the Doctor and Donna, and Bex and Brian very quickly, it was difficult to figure out what was going on. Bex and Donna also have a very similar vocal quality (and to my American ear, though they had different accents, they sounded similar), making it even more difficult to figure out who I was listening to after a scene change. My husband felt the same way, so I'm glad I wasn't alone. However, this confusion disappeared pretty quickly, especially as Donna and Bex got together and Jill started devolving, and the scenes set up the central conflict very well and at a good pace.
The main conflict in the story (the invasion by the Koggnosenti) was pretty vanilla and uninteresting, but the method was brilliant. I love that the infrasound affected people differently depending on their experiences, exposure, intelligence, and, in the case of Kevin, genetics (I suppose), and the story explored each one of their experiences. I also love that the Doctor was not immune to it - it's so easy to make him immune and therefore the only person able to solve the problem. The loss of use of the sonic was a clever way to demonstrate that he was losing it, and gave us the opportunity to figure out the problem before he did. (No, I didn't.) It also gave him the opportunity to suffer, which is something that Ten always tends to do in his stories. (He certainly suffers a lot in these three stories - physically in two and emotionally in one.) And boy, did DT take the opportunity to suffer on-camera (on-mic?) - almost to the point of chewing the scenery. Donna's role was to keep everyone together and moving, which is really what she excels at.
Bex and Kevin were great additions to the adventure, though their part of the story was a little too cleanly tied-up. Actually, in general, the entire story was too cleanly tied-up. I didn't like the "it's amazing what humans will forget" explanation for people not remembering that this happened - it harked back to the stupid explanation in the same vein at the end of "In the Forest of the Night" ("People will just forget about the entire planet being covered by trees, including the flippin' oceans" despite the prevalence of camera phones and such in today's society) so that they could have people forget about the Cybermen murdering people across the globe a few years ago, just to have that inane scene in "Death in Heaven" of people taking selfies with them. A much more plausible explanation would be that the infrasound blocked long-term memory (which it did, really - not only were people not understanding the technology in front of them, they were unable to remember what the objects did).
One thing I did notice was that they made an attempt to include as many Doctor and Donna tropes as possible: the Doctor saying "I'm sorry", Donna and her temp skills, the Doctor spewing technobabble, the two being asked if they're a couple and them vehemently denying it, the Doctor giving the bad guys the choice to stand down. I felt very much like this story was meant to announce, "The Tenth Doctor and Donna are back, and they are just like you remember!" They did a good job of it, while also giving us a fun adventure.
I'd give this story a 7/10. (Note: On my scale, most of series 4 is 7/10; Fires of Pompeii gets a 9; the Library gets an 8. Midnight gets a 10.)
