@WattWeKnow If you're interested in log-type transmission loss models, you should see: espis.boem.gov/final%20report… section 3, p. 28. These can be good for shallow water, and can be done in a spreadsheet!

@WattWeKnow Good question. No. The blog post only looks at source geometry and ignores variations in the environment (sediment type/layers, soundspeed profile, temperature, etc).

Source geometries for modelling piledriving - a midweek ponder: dbsealtd.blogspot.com/2020/07/piledr…

@Equinor & @Irwin_Carr co-created a (free) tool for rapid design choice assessment of noisy activities. dbsea.co.uk/news/

A great video from #realengineering on the tidal power potential of Ireland and UK youtube.com/watch?v=CIYA6J…

One value to rule them all: speculation on Kurtosis-weighted SEL dbsealtd.blogspot.com/2019/08/kurtos…

A single dB-value to rule them all!? What is kurtosis anyway? dbsealtd.blogspot.com/2019/08/kurtos…

We've updated our look at what matters when you model dbsealtd.blogspot.com/2019/07/more-d…

What happens as you increase the model complexity? dbsealtd.blogspot.com/2019/07/more-d…

We're especially excited to get recordings of this type of equipment. Maybe we can model a whole farm? #an2019

Last day at the stall - well have to clear for the disco tonight. We wonder if we will get TTS!? @MARSHALL_DAY #an2019

24 harbour porpoises show avoidance at mean level of 162.8 dB SEL (single strike) #an2019

New thinking at #an2019 on "Effective quiet". Max level that will never cause hearing impairment (suggested levels in image). (Effective quiet is not intended to address masking)

That bump at 20Hz is fin whales! Background noise in north west Atlantic, Feb and Aug. #an2019

Looking forward to large review of #marine #noise in Jan 2020 by Bob Gisiner at al. #an2019

This should be good! #an2019 W/ @DYKsloth

This agent based modelling reminds us of: dbsealtd.blogspot.com/2019/04/unpred… #an2019 Looking forward to finishing our Monte-Carlo agents module as well as the other moving receiver module! Come see in coffee break 😉

We're at a coffe break at #an2019 Uw noise propagation modelling and audio analyses by @MARSHALL_DAY

Just some of the new info on hearing tresholds to incorporate are presented at #an2019 #minkewhale #beardedseal (sorry for poor image) also further support for NOAA/NMFS 2018 limits and Southall 2019.

First morning at @AquaticNoise Exited!
