I would like to name all legends with a colored line, instead of only data1 and so on.
Furthermore i would like to exclude the legends with a triangle.
My code for the legend was:
legend('show')

It might help if you post the code that generated the figure in your question.

I am not certain what you want, however the approach in Specify Legend Labels During Plotting Commands (using the 'DisplayName' name-value pair) could be appropriate.

It seems Walter saw this before I did (sleeping) so I will not proceed further.
I could not run your code since I do not have the necessary data, and that makes it difficult to determine an appropriate solution. The best I could do was to refer to what were likely the most appropriate parts of the documentation, and then let you experiment with it.

plotHandles(k) = plot (level,vas,'color',C{k}, 'Linewidth',1,...
'DisplayName', 'Breaking Glass',...
'DisplayName', 'Car Horn',...
'DisplayName','Clapping');
Only the last 'DisplayName' option in a plot() call with have any effect, even if the call is generating multiple lines.
You also really only want a summary legend, not a legend for each subplot. The easiest way to handle that is to fake it.
%%%%% ---- Plot loudness --- %%%%%
% Build nested for loop that iterates through each subject with their
% corresponding sounds:
% Make new figure and place on screen Breite/Höhe
hFig = figure( 2 );
set( hFig, 'Position', [400, 300, 1250, 700], 'Name', 'Loudness Curves');
% Define papersize for export
set( hFig, 'paperunits','centimeters','Paperposition',[ 0 0 10 4])
% Set Names of subjects:
names = {'Subject 1 Old','Subject 2 Old','Subject 3 Young','Subject 4 Young',...
'Subject 5 Young','Subject 6 Young','Subject 7 Young','Subject 8 Young'};
% Set 14 different colors:
C = {'b',[0 0.4470 0.7410],[0.3010 0.7450 0.9330],'c',[0.6350 0.0780 0.1840],'r',[0.8500 0.3250 0.0980],...
[0.9290 0.6940 0.1250],'m','k','g',[0 0 .2],[0 .1 .4],[.1 .2 .3]};
for i = 1:length(fn_subjects)
subplot(3,4,i)
for k = 1:length(fn_sound)
sounds = (vas_cell{i,1}.loudness(k).Sound);
level = (vas_cell{i,1}.loudness(k).Intensity);
vas = (vas_cell{i,1}.loudness(k).VAS);
hold on
plot (level,vas,'color',C{k}, 'Linewidth',1);
title(names{i})
xlim([60 100])
xlabel('Level / dB SPL', 'FontSize', 12)
ylabel('Visual Analog Scale', 'FontSize', 12)
set(gca, 'FontSize', 12)
grid on
tone = AbsorbanceMEMR.(fn_subjects{i}).(fn_sound{k});
[FreqBand, Levels] = size(tone);
for j = 1:length(level)
maximum = max ( abs (tone(2:5,j)));
if maximum >= 0.03
plot(level(j), vas(j),'k^','MarkerSize',6)
end
end
end
sgtitle('Loudness')
end
for K = 1 : 3
plotHandles(K) = plot(nan,nan,'color', C{K});
end
lgd = legend(plotHandles, {'Breaking Glass','Car Horn','Clapping'});
lgd.Position(1) = 0.375;
lgd.Position(2) = 0.235;
lgd.NumColumns = 8;
title(lgd, 'Sounds')
