Buzzing Sound Acura Legend 1994 at 70+mph

Just started today on my 94 Legend L with 132,000 miles on it— at 70 mph+ I hear a buzzing (like bees) coming from behind the gauges on the driver side.

I just had my alternator and belts replaced around 1 week + ago. I will post a video of the noise. Sounds like a buzz flies or bees would make. Not sure what it is? (Speedometer cable?). Again, coming from right behind all the gauges on the driver side.

Here is link to video for the the noise:
