Sound in operational context

Model receive level with the environment, depth and track attached.

Build propagation cases from analysed recordings, SPL results or entered frequency-level tables, then compare environmental scenarios and detection ranges.

Model inputs

Use the acoustic data the trial actually produced.

Propagation modelling can begin from a recording analysis, an existing SPL result or a table of SPL and frequency values. This accommodates received hydrophone data as well as source levels derived from voltage measurements and a transmitting-voltage-response curve.

Frequency range choice

Display range can follow a focus frequency or the complete set of analysed median frequencies, which matters when multiple bands produce materially different ranges.

Environmental comparison

Select bottom types and sea states as comparison scenarios, filter the displayed results and export each combination in an organised workbook or CSV structure.

Detection criterion

Apply a minimum receive level so the table and graph distinguish detectable and non-detectable range points.

Map and water column

Connect the calculation to where and when it occurred.

GPS tracks

Match analysed files or time-varying source levels to a vessel track.

Fixed sources

Represent stationary pingers or receivers at project positions.

Sparse sonar trials

Display separated pings in time rather than implying continuous transmission.

Variable LFM levels

Preserve changing source or receive levels between transmitted pulses.

CTD profiles

Use imported water-column profiles as environmental context for deployment review.

Source and receiver depth

Compare recommended deployment depth with the depths actually used.

Model the trial—not an abstract source.

Bring the SPL, frequency, timing, positions, depths and CTD profile available for your project.
